You may be looking for memory-proof.

What Cousin Eliza once referred to as "history-proof[ing]" (AUDIO: The Ship of a Billion Years ^[+]Loading...["The Ship of a Billion Years (audio story)"]) was the ability that allowed individuals to perceive alterations and changes to time; (TV: Flesh and Stone ^[+]Loading...["Flesh and Stone (TV story)"], Cold Blood ^[+]Loading...["Cold Blood (TV story)"], etc.) the chronology of the changes in time itself was known as meta-time, with an entire field of study existing around this concept, known as meta-history. (PROSE: Love & War ^[+]Loading...["Love & War (short story)"]) One account treated the existence of memories persisting after a rewrite of a timeline as temporal echoes. (PROSE: Playing in the Ninth Doctor's Era ^[+]Loading...{"page":"22","1":"Playing in the Ninth Doctor's Era (feature)"}) Among academics, the names Temporal Web Resistance and History-Persisting were posited but Mnemosyne prevailed; these academics conflated the persisting memories with physical artefacts remaining after they "un-occurr[ed]" as all the same, specific phenomenon. (PROSE: "Of Facdocksparation & Mnemosyne" ^[+]Part of The Druimport Entwister No. 284, Loading...{"name":"\"druimport284\"","page":"1","namedpart":"Of Facdocksparation & Mnemosyne","1":"The Druimport Entwister No. 284 (short story)"})

The ability was often associated with déjà vu (AUDIO: UNIT Dating ^[+]Loading...{"timestamp":"00:35:35","1":"UNIT Dating (audio story)"}) and the Mandela Effect. (PROSE: The Mandela Effect, Or Monsters on the Streets of London ^[+]Loading...["The Mandela Effect, Or Monsters on the Streets of London (short story)"])

Nature

Academics suggested that Mnemosyne was "borne out of some as-yet-unknown property of the fabric of spacetime." (PROSE: "Of Facdocksparation & Mnemosyne" ^[+]Part of The Druimport Entwister No. 284, Loading...{"name":"\"druimport284\"","page":"1","namedpart":"Of Facdocksparation & Mnemosyne","1":"The Druimport Entwister No. 284 (short story)"})

Individuals with the ability

As an ability possessed by time travellers

According to the Eleventh Doctor, being a time traveller "change[d] the way you see the universe, forever," which allowed individuals to perceive changes to time, such as entire individuals being erased from time by the cracks. (TV: Flesh and Stone ^[+]Loading...["Flesh and Stone (TV story)"]) Ace had the ability to sense temporal distortions due to having crossed the time field "dozens" of times; it made her akin to "a sphere talking to a circle." (PROSE: Set Piece ^[+]Loading...{"name":"\"SetPiece\"","chaptname":"In Taberna","page":"93-94","chaptnum":"6","1":"Set Piece (novel)"})

The Eighth Doctor once explained that, in order to have the "necessary time travel chops" to remember previous versions of history, one had to be protected by a machine capable of time travel, such as his TARDIS. Indeed, Liv Chenka theorised they were protected from changing memories due to her and Helen Sinclair's association with the Doctor. The Doctor identified déjà vu as an "occupational hazard" of a time traveller. (AUDIO: UNIT Dating ^[+]Loading...{"timestamp":"00:25:55, 00:28:27, 00:35:35, 00:42:36","1":"UNIT Dating (audio story)"}) Similarly, the War Doctor explained that if an individual was inside a time machine they would remember "the timelines that never were." (AUDIO: The Shadow Vortex ^[+]Loading...{"timestamp":"00:51:47, 00:53:38","1":"The Shadow Vortex (audio story)"})

The Third Doctor once explained to Jo Grant that she could resist the force that removed several individuals out of time as she travelled with him, allowing her to remember them when nobody else could. (AUDIO: Storm of the Horofax (part one) ^[+]Loading...{"timestamp":"00:28:00","part":"One","1":"Storm of the Horofax (audio story)"})

During the Great Time War, only the Higher Species, due to being higher up on the evolutionary ladder, were able to perceive the temporal changes to the histories of the Lesser Species' planets. One such Higher Species were the Forest of Cheem. (PROSE: Meet the Doctor ^[+]Loading...{"page":"21","1":"Meet the Doctor (DWAN 2006 short story)"}, GAME: "Trees of the Forest of Cheem" ^[+]Part of The End of the World, Loading...{"page":"57","namedpart":"Trees of the Forest of Cheem","1":"The End of the World (game)"})

As an ability possessed by ordinary people

In some accounts, even ordinary people who had never travelled through time were able to remember alterations to history.

In fact, upon research into Mnemosynchronicity, academics dispelled the previously established belief that only those who travelled spacetime or were time sensitive could be "aware of the replacements and amendments caused to time"; rather, such an ability was further present in those not deliberately protected and/or genetically predisposed. (PROSE: "Of Facdocksparation & Mnemosyne" ^[+]Part of The Druimport Entwister No. 284, Loading...{"name":"\"druimport284\"","page":"1","namedpart":"Of Facdocksparation & Mnemosyne","1":"The Druimport Entwister No. 284 (short story)"})

The Eleventh Doctor once explained that everyone had "memories of a holiday they couldn't have been on or a party they never went to, or met someone for the first time and felt like they've known them all their lives"; he considered everyone's memory to be a mess, as time was being rewritten daily. (HOMEVID: Good Night ^[+]Loading...["Good Night (home video)"])

Andrea Talwinning was mostly unable to remember the alterations to her timeline other than knowing that it didn't make any logical sense, while the Seventh Doctor and Bernice Summerfield could. It was unclear if Talwinning's memory augmentation contributed to this or not. (PROSE: Continuity Errors ^[+]Loading...{"page":"238","1":"Continuity Errors (short story)"})

Professor Grey speculated that the Mandela Effect, a phenomenon experienced by many people on Earth, was actually caused by "another timeline that ha[d] subsequently been ‘rewritten’." (PROSE: The Mandela Effect, Or Monsters on the Streets of London ^[+]Loading...["The Mandela Effect, Or Monsters on the Streets of London (short story)"])

Unnatural methods

In some accounts, it was an aberration even for time travellers to remember alterations to time, and thus could only possess the memories through unnatural methods.

The Ninth Doctor claimed that the memories of erased events were normally repressed and their surfacing to be a glitch. Rose Tyler's memories of a "redundant timeline" (COMIC: The Bidding War (part two) ^[+]Loading...{"part":"Two","1":"The Bidding War (comic story)"}) fractured her mind, putting her at the cusp of a psychotic episode. (COMIC: The Lost Dimension (part two) ^[+]Loading...{"part":"Two","1":"The Lost Dimension (comic story)"}) A linked account showed that the users of Eradicator X7s were given the ability to remember the targets that it erased from time. (COMIC: Secret Agent Man ^[+]Loading...["Secret Agent Man (comic story)"])

The Eleventh Doctor explained to Clara Oswald that she would not remember the events of the past day after he reversed that timeline, as "time [could] mend anything." (TV: Journey to the Centre of the TARDIS ^[+]Loading...["Journey to the Centre of the TARDIS (TV story)"]) Exceptionally, these memories were awoken in Clara as she travelled through the ruins of a future TARDIS, by the telepathic circuits. (TV: The Name of the Doctor ^[+]Loading...["The Name of the Doctor (TV story)"], GAME: The Name of the Doctor ^[+]Loading...{"page":"238","1":"The Name of the Doctor (game)"}) A later account explained that the telepathic circuits itself retained memories of deleted timelines. (PROSE: "Technology" ^[+]Part of Whotopia: The Ultimate Guide to the Whoniverse, Loading...{"namedpart":"Technology","1":"Whotopia: The Ultimate Guide to the Whoniverse (reference book)"})

Unclear

In some accounts, people were shown to possess the ability through natural or unnatural means that didn't necessarily preclude any of the previous methods.

In an account where the extent of those who had the ability was unclear, at least one time sensitive was known to have it, aside from the Eleventh Doctor. (COMIC: Assimilation² ^[+]Loading...["Assimilation² (comic story)"])

A Verron puzzle box could protect whoever held it from changes to time. (TV: Whatever Happened to Sarah Jane? ^[+]Loading...["Whatever Happened to Sarah Jane? (TV story)"])

One account claimed that the Eighth Doctor's ability to see into peoples' futures was due to the memories of potentially thousands of alternative timelines all being rewritten by the Time War. (PROSE: Designing Eighth Doctor Adventures ^[+]Loading...{"page":"16","1":"Designing Eighth Doctor Adventures (feature)"}) Another account instead attributed this ability to his Time Lord nature. (PROSE: The Queen of Eros ^[+]Loading...["The Queen of Eros (short story)"])

Extent and limitations

Individuals with this ability were naturally aware if parts of their histories retroactively changed, such as having experiences that didn't originally happen be injected into their lives; (PROSE: Bafflement and Devotion ^[+]Loading...["Bafflement and Devotion (short story)"], TV: A Christmas Carol ^[+]Loading...["A Christmas Carol (TV story)"], HOMEVID: Good Night ^[+]Loading...["Good Night (home video)"], etc.) In one account, the Eleventh Doctor claimed that as Amy Pond's history had been altered by the death of Rory Williams, she had to concentrate on the memories to preserve them. (TV: Cold Blood ^[+]Loading...["Cold Blood (TV story)"])

For those who didn't possess the ability, or had something in their own timeline changed, forgetting the memories was not instantaneous; (TV: Cold Blood ^[+]Loading...["Cold Blood (TV story)"], The Church on Ruby Road ^[+]Loading...["The Church on Ruby Road (TV story)"], PROSE: The Church on Ruby Road ^[+]Loading...{"name":"\"novelisation\"","page":"119-126","chaptnum":"Sixteen","1":"The Church on Ruby Road (novelisation)"}) Andrea Talwinning experienced the process in a fleeting moment, as a "whole new past unfold[ed] in her mind," with her old memories "melting away." (PROSE: Continuity Errors ^[+]Loading...{"page":"235","1":"Continuity Errors (short story)"})

In the subconscious

Vestiges of memories would often manifest as subconscious emotions, such as chills, (PROSE: Continuity Errors ^[+]Loading...{"page":"214-239","name":"\"errors\"","1":"Continuity Errors (short story)"}) fear, (AUDIO: Recruits ^[+]Loading...["Recruits (audio story)"]) suspicion, (PROSE: Loose Ends 3: The Regency ^[+]Loading...["Loose Ends 3: The Regency (short story)"]) sorrow, (TV: The Church on Ruby Road ^[+]Loading...["The Church on Ruby Road (TV story)"]) and a craving for pasta. (PROSE: Taste the Noodles of Dracula ^[+]Loading...["Taste the Noodles of Dracula (short story)"])

As dreams

Memories of altered history often would exist as dreams or nightmares.

The Eighth Doctor remembered the prior version of his defeat of Dronid criminal Skagra during his fourth incarnation during a dream (WC: Shada ^[+]Loading...["Shada (webcast)"], AUDIO: Shada ^[+]Loading...["Shada (audio story)"]) due to presumed temporal instabilities (PROSE: A Brief History of Time Lords ^[+]Loading...{"chaptname":"Novices of the Untempered Schism","chaptnum":"4","1":"A Brief History of Time Lords (novel)"}) caused by Borusa's failed attempt to extract the Fourth Doctor from his time stream. (TV: Shada ^[+]Loading...["Shada (TV story)"])

The Eighth Doctor once told Charlotte Pollard, who once had contradictory sets of memories for different versions of history, that her memories would subside when she next slept, with some remaining as memories, some as stories and some as dreams. (AUDIO: Seasons of Fear (part four) ^[+]Loading...{"part":"Four","1":"Seasons of Fear (audio story)"})

Evelyn Smythe was able to remember an alternate timeline as a horrific dream whenever she tried to sleep. The Sixth Doctor explained that those events had not been truly erased as they continued to live on as dreams, as nightmares, as shadows. People wouldn't dare acknowledge these as anything other than fantasy, as it was preferable than to acknowledge the atrocities they could commit. The Doctor hoped that people would take a warning from these shadows, as to not repeat the evils they once did. (AUDIO: Jubilee (part four) ^[+]Loading...{"part":"Four","1":"Jubilee (audio story)"})

Rose Tyler suspected Donna Noble dreamt about her travels with the Tenth Doctor in the version history that was overwritten by a parallel world. Later, after the negation of this world, Donna remembered it like a dream slipping away. (TV: Turn Left ^[+]Loading...["Turn Left (TV story)"])

Esme could remember one undone timeline like a mostly-forgotten, "queer" dream. (PROSE: Teddy Sparkles Must Die! ^[+]Loading...{"page":"102","1":"Teddy Sparkles Must Die! (short story)"})

Bernice Summerfield's memory of learning of the Armano Graffito during her education, an event that happened in a revised version of history, felt as "though she had dreamed it", or that it hadn't been there before. (PROSE: Set Piece ^[+]Loading...{"chaptname":"Yesterday, I Was Mad","page":"69","chaptnum":"5","1":"Set Piece (novel)"})

Other

Ishmael's memories of his former life as Dra'Heem came to him as visions. (AUDIO: Call Me Ishmael ^[+]Loading...["Call Me Ishmael (audio story)"])

Relationship to time

Memory had a special relationship to time. Different versions of history would continue to exist as memory, (AUDIO: Jubilee (part four) ^[+]Loading...{"part":"Four","1":"Jubilee (audio story)"}) and through their underestimated power, they could be used restore erased things back into existence, such as the Doctor and the universe itself. (TV: The Big Bang ^[+]Loading...["The Big Bang (TV story)"]) Indeed, a unique TARDIS was once born from a projected memory, and so the Fifteenth Doctor equated time and memory as one and the same. (TV: The Legend of Ruby Sunday ^[+]Loading...["The Legend of Ruby Sunday (TV story)"])

Within the Inner Reference Room of the Multiplicity, the flowers that grew aside the tree of time were "scented in memory". (PROSE: {{esquivalience}} ^[+]Loading...{"page":"14","1":"esquivalience (novel)","2":"'\"`UNIQ--nowiki-0000007A-QINU`\"'"})

Physical artefacts

Main article: User:Epsilon/Physical artefacts of altered history

Memory wasn't the only thing that could survive time being changed, as unaccountable little traces were left of the "people who fell out of the world", such as faces in photographs, luggage, and half eaten meals. (TV: The Pandorica Opens ^[+]Loading...["The Pandorica Opens (TV story)"]) Some notable examples included Rory Williams's engagement ring (TV: Cold Blood ^[+]Loading...["Cold Blood (TV story)"], The Lodger ^[+]Loading...["The Lodger (TV story)"], The Pandorica Opens ^[+]Loading...["The Pandorica Opens (TV story)"]) and a photo of Rory dressed up as a centurion and Amy Pond and a police officer. (TV: The Pandorica Opens ^[+]Loading...["The Pandorica Opens (TV story)"])

The research done by academics in Mnemosynchronicity following an incident at the Intergalactic Records Association found that the physical and mental evidence of that un-occurred were facets of the same whole. (PROSE: "Of Facdocksparation & Mnemosyne" ^[+]Part of The Druimport Entwister No. 284, Loading...{"name":"\"druimport284\"","page":"1","namedpart":"Of Facdocksparation & Mnemosyne","1":"The Druimport Entwister No. 284 (short story)"})

History

This section is not ordered by standard chronological order but rather an approximate chronological meta-time order.

Pre-War era

Due to the damage of Arianda's spaceship, time energy removed Major Paul Hardy and two of Commander Burton's marines from time. The Third Doctor, in conversation with Burton, naturally didn't forget them and was initially confounded as to why Burton couldn't. He turned to Paul, only to discover he too wasn't there, and asked Jo if she had seen him. She was at first unsure as to whom the Doctor was referring to, but upon saying his name she remembered him and couldn't conceptualise not remembering him. The Doctor soon concluded what had happened. (AUDIO: Storm of the Horofax (part one) ^[+]Loading...{"timestamp":"00:27:25","part":"One","1":"Storm of the Horofax (audio story)"})

Doris and Alistair Lethbridge-Stewart discover that the Doctor changed time and attended their wedding, recalling both versions of the event. (PROSE: A Romantic Evening ^[+]Loading...["A Romantic Evening (short story)"])

Sometime in the 1990s, (TV: Battlefield ^[+]Loading...["Battlefield (TV story)"], etc.) Doris Lethbridge-Stewart spent one winter evening by the fire leafing through photographs of her wedding; she got Alistair's attention when she noticed that the Seventh Doctor had appeared in many of the photographs despite not having originally attended the wedding. To their surprise, they both then recalled a version of their wedding with the Doctor, Doris realising that her apology to him the previous summer about not inviting him spurred him to change time and attend. (PROSE: A Romantic Evening ^[+]Loading...["A Romantic Evening (short story)"])

Andrea Talwinning, a Librarian at the New Alexandria Library in 2668, began to experience her life be rewritten by the Seventh Doctor after she refused him access to a book about the genocide of the Deltherons. She immediately began having inexplicable thoughts of things she didn't previously know, and, as she spoke to Bernice Summerfield, had a chill when the phrase "rewriting the past" was used. Benny was aware that Andrea's appearance had also shifted in the space of five minutes. She soon came to have a vague understanding of what had happened as she deduced her life had become illogical through various contradictions, even though she couldn't consciously remember what her life used to be like. When the Doctor attempted once more to ask her for access, she confronted him, maintaining her stance despite her gratitude for the survival of her daughter who she correctly suspected had originally died. (PROSE: Continuity Errors ^[+]Loading...{"page":"214-239","name":"\"errors\"","1":"Continuity Errors (short story)"})

In 1366BCE Egypt, Ace changed history by creating the Armano Graffito as a message to Bernice, who was concurrently in the 18th century; in this revised version of history, Bernice had a classroom memory of the Graffito, which had persisted as a famous archaeological puzzle into her home time, hundreds of years in the future. Yet Bernice, upon recalling this memory, found it to be strange, as if it were from a dream or rather that it had not been there before.

Ace herself, having "crossed the time field dozens of times", was able to sense a temporal distortion as she went to investigate a space-time rift near Akhenaten in the past. As she dismounted her chariot, she and Sesehaten were subjected to a minor time loop. Sesehaten was unaware of the looping. (PROSE: Set Piece ^[+]Loading...{"chaptname":"Yesterday, I Was Mad\", \"In Taberna","page":"69, 93-94","chaptnum":"5 & 6","1":"Set Piece (novel)"})

Preceding the Game of Rassilon, Borusa's attempt to use a Time Scoop to excise the first five Doctors from their time streams partially failed, leaving the Fourth Doctor and Romana II unable to be fully extracted and left in a limbo-like state; (TV: The Five Doctors ^[+]Loading...["The Five Doctors (TV story)"]) due to these temporal instabilities, as theorised in A Brief History of Time Lords, the subsequent events unfolded four different times with two different incarnations of the Doctor. (PROSE: A Brief History of Time Lords ^[+]Loading...{"chaptname":"Novices of the Untempered Schism","chaptnum":"4","1":"A Brief History of Time Lords (novel)"}) In the version of events involving the Eighth Doctor, memories of the prior iteration of these events involving the Fourth Doctor arose in his dreams. When he told Romana about this, in his successful attempt to resume the course of history, she initially believed that the events had been prevented from happening in the first place, but his memories disproved this. (WC: Shada ^[+]Loading...["Shada (webcast)"], AUDIO: Shada ^[+]Loading...["Shada (audio story)"])

For a while, the Eighth Doctor travelled with Iris Wildthyme in her bus; on one trip through the time-space vortex, the duo meta-fictionally discussed their conflicting memories, often in relation to Doctor Who; the Doctor had a somewhat narrow-minded approach, keen to solve the definitive version of events, whilst Iris took a liberal approach, understanding that their lives were "a series of stories that involve paradoxes, time travel, mind control, virtual selves, cloning, regression, reincarnation, talking vegetables, cybernetics, regeneration, prolepsis, analepsis, alternative dimensional instabilities, metatextuality, allegory, satire, fantasy, revisionism, cliches, plagiarism and hoodwinkery." Despite his views, the Doctor was well aware his "already-troubled time stream" was subject to "[someone] slipping in extra adventures". He realised in horror that this meant his life was being elasticated, thus making him immortal. (PROSE: Bafflement and Devotion ^[+]Loading...["Bafflement and Devotion (short story)"])

Bernice once wrote a letter to her "Dear Friend", to thank him for taking her across time as it led to a sequence of events involving her becoming a mother. In this letter, she admitted that, while she could remember being on Earth during the Second World War, she couldn't "remember whether you were with me or if I was just hoping you were," (PROSE: Dear Friend... ^[+]Loading...["Dear Friend... (short story)"]) matching a set of accounts where Bernice was present in Guernsey 1941 with the Seventh Doctor (PROSE: Just War ^[+]Loading...["Just War (novel)"]) or her husband Jason Kane. (AUDIO: Just War ^[+]Loading...["Just War (audio story)"]) Indeed, there were conflicting historical records on this matter, as well as another which claimed that Bernice had thirteen half-immortal children by the last survivor of a race of time travellers, (PROSE: Paydirt ^[+]Loading...["Paydirt (short story)"]) corresponding to an account depicting an altered state of reality where all of the Doctor's life took place at the same time. (PROSE: The Infinity Doctors ^[+]Loading...["The Infinity Doctors (novel)"]) This was a matter of contention among a group of archaeologists in the 46th century, who debated the veracity of these records among many other highly conflicting accounts of Bernice's life. An aged Bernice, under the alias "Professor Kent", claimed that these accounts were based in truth despite them becoming warped throughout the millennia. However, her eyes physically shifting colour from blue to brown to green suggested something temporal was at work, and one archaeologist couldn't decide on the colour of her eyes after seeing this phenomenon. (PROSE: Paydirt ^[+]Loading...["Paydirt (short story)"])

When Sebastian Grayle returned to 305AD to kill the Eighth Doctor, at the Roman fort where his younger self's journey into immortality began, his younger self became horrified at what he would become and proceeded to kill his future self. He created a new version of history where he did not become immortal and hunted the Doctor, but rather lived his life with his love Julia with money gifted to him by the Doctor. Charlotte Pollard then questioned how this was possible due to the paradox, but the Doctor explained that this new version of history could overwrite the original due to the temporal disruption caused by Grayle's allies, the Nimons, and time healed itself to compensate for how they arrived in 205AD. Charley found her head to be filled with different, contradictory memories of both versions of history, and the Doctor explained that these would last until she next slept, with her "know[ing] some as memories, and some of them as stories, and some of them as dreams." He concluded by saying "the tides of time will wash us all clean." (AUDIO: Seasons of Fear (part four) ^[+]Loading...{"part":"Four","1":"Seasons of Fear (audio story)"})

After the nullification of an alternate timeline wherein the English Empire took over Earth with Dalek technology, Nigel Rochester, who had died, was restored to life and recognised the Sixth Doctor as he rushed to his aid, suffering from a heart attack. Later, Evelyn Smythe found that whenever she tried to sleep, she dreamt of the version of herself starving to death in the Tower of London. The Doctor explained that the alternate timeline wasn't entirely erased as it continued to exist on in people's memories, in the shadows, remembered as a warning against the atrocities they were capable of committing. (AUDIO: Jubilee (part four) ^[+]Loading...{"part":"Four","1":"Jubilee (audio story)"})

Due to temporal slippage, the exact date of when Sarah Jane Smith and the Third Doctor worked for UNIT shifted between the 1970s and 1980s. In 1996, when Sarah attempted to recall her time with the Third Doctor, she realised that she remembered both decades; the Eighth Doctor explained the cause of this phenomenon to her. (PROSE: Interference - Book Two ^[+]Loading...{"chaptname":"Cool","name":"\"interference\"","chaptnum":"24","1":"Interference - Book Two (novel)"})

War era

War in Heaven

Examining a set of hieroglyphs during the War, several members of the Society of Sigismondo di Rimini attempted to keep appraised of what was happening to Justine at the Osirian Court. As the Osirian Court had a special relationship to the timeline of the wider universe, only Eliza could follow the narrative as it changed, while John Pennerton only ever remembered the most recent version of the text. Eliza explained that it was because, as a member of Faction Paradox, her memory was "history-proofed". (AUDIO: The Ship of a Billion Years ^[+]Loading...["The Ship of a Billion Years (audio story)"])

As a "loyal soldier" of the House Military, Dionus was part of the battle fought over Golgalith, a nexus world. However, when he saw the effect the War had on the planet's natives — how life was warped into death and vice versa, and many other overlapping, contradictory possibilities, due to the timelines being manipulated — he became disillusioned with the Homeworld, saw their propaganda for what it was and he became a renegade. One of the most horrifying things he saw was a person's minds shatter upon gaining and remembering five hundred timelines. (AUDIO: Eternal Escape ^[+]Loading...{"timestamp":"00:03:09","1":"Eternal Escape (audio story)"})

Setting up residence on Gulliver's Rest to escape his past and to make amends, Dionus began treating those with temporal diseases. (AUDIO: Eternal Escape ^[+]Loading...{"timestamp":"00:06:07","1":"Eternal Escape (audio story)"}) An individual came to Dionus, known as "Ishmael", with a problem: he had been experiencing visions of another person's life, Dra'Heem. Dionus went through the possibilities first, ruling out almost all of them before entering Ishmael's mind. There he explored Ishmael's memories of Dra'Heem's execution and childhood, and then Ishmael's own memories of being brutally trained by the Order of Tarth'Rioshim and his first kill. Bot finding what he needed, Dionus pushed into Ishmael's subconscious. He uncovered a lost memory of Dra'Heem's mother giving Ishmael to the Order, which gave him the link to understand that Ishmael's life existed as a rewritten version of Dra'Heem's in the new timeline where the planet Urok'Sharn was brought back into its existence after its earlier destruction. (AUDIO: Call Me Ishmael ^[+]Loading...["Call Me Ishmael (audio story)"])

When Maroth Rak’Nah came under Dionus's employ, she began group therapy sessions for many of the temporal refugees. In one such session, several refugees gave their stories of time being rewritten: Raggeron G’Rim — a monk of the charitable Phanderel Chapter — one day awoke to find it had become a fanatical terrorist order bent on "cleansing" sinners, and Julia Smith — a human born on the free and democratic planet Faunus, who attended the University of New New Amsterdam — one day found that it had been replaced by a totalitarian society who worshipped the Warden. (AUDIO: The Healer's Sin ^[+]Loading...{"timestamp":"00:04:50","1":"The Healer's Sin (audio story)"})

Dionus forgot his wife Susit after she was erased by Faction Paradox in revenge for him not accepting a deal they proposed. When the War came to Gulliver's Rest, Dionus didn't bother packing anything when he attempted to escape with his family, as the contents not only could be altered by the changes in time, he didn't believe they could even remember it, although he did remember the environment of the planet and his neighbours after they were re- and unwritten. He, however, did not remember his children Meren and Egar when they became Tara, nor did he remember her when she was erased from time just before he escaped in his timeship. (AUDIO: Eternal Escape ^[+]Loading...["Eternal Escape (audio story)"])

Due to Mother Mathara's interference in Gallifrey's history using the biodata virus, on the day before the War in Heaven begun, the Panopticon shrunk as history changed and important figures from Time Lord society were erased from history. While Fitz Kreiner remembered that the Panopticon was meant to have six sides, to represent the six colleges of cardinals, Romana III's personal timeline shifted such that it had always had five-sides, than four-sides, than three-sides, before having always been but a circular room. (PROSE: The Ancestor Cell ^[+]Loading...["The Ancestor Cell (novel)"])

Mother and Father, watching the destruction of the corrupted War Queen's Homeworld through a loa ritual, observed how any survivors of this Homeworld took sanctuary on other cloneworlds or with the Lesser Species; this seemed to be futile, as their hearts decayed in their chests and their timelines "rott[ed] into thorned patchworks of broken memories." (PROSE: The Story So Far... ^[+]Loading...["The Story So Far... (short story)"])

After the War in Heaven was averted by the destruction of Gallifrey, one account suggested that the surviving Time Lords of the Post-War universe were unable to recall their heritage or many of their memories due to the shift in their personal timelines. (PROSE: The Adventuress of Henrietta Street ^[+]Loading...["The Adventuress of Henrietta Street (novel)"])

Last Great Time War

During the Great Time War — specifically an early version fought in the Vortex and the Ultimate Void — the Lesser Species were on the whole unaware of the conflict; when the histories of their planets were distorted and disrupted by the rupturing Vortex, only the Higher Species — those higher up on the "evolutionary ladder" — were able to see these changes. The Forest of Cheem, for one, wept upon seeing the bloodshed. (PROSE: Meet the Doctor ^[+]Loading...{"page":"21","1":"Meet the Doctor (DWAN 2006 short story)"})

According to an account in which the Time War had both ended and restarted prior to the regeneration of the Seventh Doctor, the Eighth Doctor's amnesia after regenerating was a possible side effect of his many births in the "ever-changing timeline". Furthermore, his ability to see into the future of the personal timelines of the people he met was attributed to the Time War rewriting history, as he was actually remembering events that occurred in potentially thousands of alternative timelines. The Doctor's also had memories that no longer matched his own history, after his discovery that the Catalyst had been responsible for restarting the Time War. (PROSE: Designing Eighth Doctor Adventures ^[+]Loading...{"page":"16","1":"Designing Eighth Doctor Adventures (feature)"}) However, the Doctor was unable to remember the moment when he was shot with a Temporal Exterminator, which unravelled and corroded his timeline in both directions. (GAME: Doom of the Daleks ^[+]Loading...{"page":"36-38","1":"Doom of the Daleks (game)"})

While trying to not be a part of the Time War, the Eighth Doctor took Sheena to be his companion, travelling to the cruise spaceliner Theseus. Due to a rapidly increasing number of alterations to the timelines, many things around the Doctor began shifting and he could invariably remember fragments of what was before. He didn't initially realise his companion Sheena became Emma, but still remembered she was called Emma when she became Louise. When she told him that wasn't her name, he remembered that it was Sheena, but she corrected him to her current name, although hesitating while doing so, evidently not entirely confident in her memory. He was terrified to discover he could not even remember how long he had been travelling with Sheena/Emma/Louise, nor "how or why or where" they met. He could vaguely remember freeing Koloth from his bonds when time shifted and he was returned to his confinement. He also remembered the ship was full of holidaymakers when time shifted again and the passengers became refugees from the Time War.

After Sheena/Emma/Louise was erased from history, he could remember her, but upon reuniting with some of the passengers he had met earlier, they told him he was alone and he agreed with them. However, he couldn't remember the current iteration of time, still remembering Captain Darvor's sacrifice of Koloth, which had shifted into a version of reality where Koloth had been willing.

On the Planet — the Ogron homeworld — the Eighth Doctor voiced how he couldn't see any good reason the Daleks would have to use Ogrons as footsoldiers. Upon the Twelve's reminder of the Ogrons' presence during the events at Auderly House, he soon realised that he had "inconceivable" conflicting memories, as he could remember the original, Ogron-less version of history and the version of history with Ogrons, due to the Overseer's interference.

On 2 April 2005, following the Dummy Massacre, Mark Young, who collected old Daguerreotype photographs from the 1840s, responded to Who is Doctor Who?'s request for sightings of the then missing Rose Tyler, reporting that he had found a family portrait with a striking resemblance to Rose.

After their first failed attempt to open the heart of the TARDIS — part of Rose's bid to return to the Game Station in 200,000 — Jackie tried telling her to give up, but Rose refuted her claim that her father Pete would've told her the same thing. Rose then tried to get Jackie to remember when Pete died, when Rose was by his side, holding his hand, to tell her she knew her father would tell her to not give up on the Doctor.

After the Cardiff Space-Time Rift splintered, numerous temporal cracks widened resulting in objects and people from other time periods appearing all over the Earth. These cracks were used as a diversion by Bilis Manger, who manipulated Torchwood Cardiff into opening the rift, thus releasing Abaddon. The rift was closed back when Abaddon was killed by Jack Harkness which also had the effect of flinging back time, resulting in everyone who had died in the incident coming back to life including Rhys Williams, who had been murdered by Bilis after being brought to the Hub, only to return at his home with no memory of having been killed.

To sustain the paradox of the Toclafane invading Earth and killing their human ancestors, the Saxon Master installed a paradox machine within the control room of the Tenth Doctor's TARDIS, which he kept within the UNIT aircraft carrier Valiant. After the Master ruled over Earth for a whole year, Jack Harkness destroyed the paradox machine, resulting in the reversal of time to just before the Toclafane invasion. This reversal, however, did not occur within the Valiant itself, which the Tenth Doctor identified as being the "eye of the storm", thus all those within it at the time of the machine's destruction remained as they were and remembered the Year That Never Was.

After the Time Beetle created a parallel world around Donna Noble, it erased all of her travels with the Tenth Doctor from time and resulted in his death. However, when speaking to Rose Tyler, who originated from the original timeline and had travelled to Donna's parallel world, suspected Donna dreamt of the Doctor and, when Rose told her she saved the Doctor's life, she had a flashback to the original version of history.

Later, after Donna negated the creation of this parallel world, she struggled to remember it when the Doctor asked her why she hugged him, as the memories were like a dream that was slipping away. She did, however, remember her encounters with Rose and the message she gave as she died — "Bad Wolf".

After travelling back in time to Stonehenge in 102, Amy confronted the Doctor about the ring. He explained that it was a trace of someone erased from time, partially debunking Amy's theory that he meant to propose to someone, but she assumed that it belonged to him for a female partner. They, and River Song, were then assisted by Roman soldiers, one of them mysteriously being a resurrected Rory who was dismayed that Amy couldn't remember him. The soliders were actually Auton duplicates, part of a trap for the Doctor created by the Alliance, as they were devised from Amy's psychic residue from her childhood home. As structures contained memories, the Roman soldiers represented her interest in Roman history, Rory created after a surviving photograph of him and Amy, and the Pandorica — the final piece of the puzzle — was created after The Legend of Pandora's Box.

As Rory's consciousness was genuinely him, however, he took back his engagement ring and begun trying to make her remember, but she already began crying barely after he introduced himself, inexplicably feeling happy. He then wrestled for his own autonomy as Amy remembered, understanding that he was physically and Auton and thus Amy was in danger. She stayed with him and he was unable to prevent himself from shooting him.

Amy later confessed to the Doctor that her life didn't make sense as she simultaneously remembered both having and not having parents, following the Doctor's reboot of the universe. The Doctor consoled her by explaining that everyone had memories of things thay didn't happen, which was really a result of time being changed daily. He decided to demonstrate the concept of having two sets of memories by taking Amy back to the day of her saddest memory, where she dropped an ice cream at a fairground in 1994.

After the conclusion of a version of the Time War involving the tenth, eleventh and warrior incarnations of the Doctor, (TV: The Day of the Doctor ^[+]Loading...["The Day of the Doctor (TV story)"]) a successive account posited a number of cases where the timelines (such as that of Earth's) as the Ninth Doctor remembered them were altered often from ripples from the Time War; he was unsure how much of what he knew of the universe had changed. It also added that many other people couldn't trust their own memories.

These included: his recollection of the Fourth Great and Bountiful Human Empire after at least being halted due to the interference of the Dalek Emperor; his memory of Harriet Jones and the golden age she ushered in being retroactively altered by his tenth incarnation's actions so that he initially struggled to remember the PM; his memories of the inconsistent dating of his third incarnation's exile on Earth being caused by Time War ripples — Earth being on a different path pre-War before being subtly changed, with the Doctor and the Time Lords mitigating any major changes resulting in, at most, the dates being "shuffled" in the stabilised current version of history; and the possibility that the Doctor's affiliation with Earth is out of a desire to ensure its history isn't disrupted, as it may have been a strategic point during the Time War and thus is unforgiving towards the population.

Furthermore, there were a series of possible scenarios involving different individuals that involved the memories of rewritten history: a UNIT team found that history was changed and UNIT was never founded, and so they set out to solve the mystery; a Time Lord and her companions were trapped in a time bubble during the Time War and, upon entering the post-War universe, she found that the histories of her companions had been erased so they begin to die — they then attempt to manipulate history into re-establish themselves, but not without consequences; and a group of Time Agents who deserted the Time Lords who hired them during the war lost their memories, but the species affected by their desertion attempt fo have their revenge.

Undated events

Davros once infiltrated the Matrix on Gallifrey to erase the Doctor from existence. The Twelfth Doctor, fading in and out of existence, soon saw the Daleks in his his memories in places they had never been. With the help of a hologram of the First Doctor, a time stasis field was placed around the TARDIS to stabilise the Doctor's timeline so that he could fix the Web of Time.

Following the Unravel, Jenny Everywhere shifted into the Third Universe and travelled to a snowy planet to rescue two Pinguis, who had had their lives rewritten by the catastrophe; whilst Jenny herself had not been witness to the pre-Unravel version of time, she nonetheless felt "in her bones" that even their names were meta-historical revisions. However, she didn't have the heart to tell them. (PROSE: A World of Pure Unimagination ^[+]Loading...{"page":"3","1":"A World of Pure Unimagination (short story)"})

Within the Multiplicity, both Head D.C. Miltontheus and Caretaker ______ possessed the ability. ______ was aware that the alphabet's originally order was "T, V, U, W", after it had been Unravelled and become "T, U, V, W". After ______ disposed of The Book of Belgian Dutch by placing it into the special disposal chute, which erased it from time, Miltontheus confronted the Dictionary Contributors about it; while ______ had no trouble recalling their actions leading up to its erasure, the other Contributors were less fortunate, as they were not only unable to remember the book, they also forgot Miltontheus's confrontation later that very same day. Some Contributors believed their work shifts had just "flown by", with such vague thoughts not even troubling them given the nature of their environment. ______ continued to remember, but elected mentally not to raise the subject.

After usurping Miltontheus by rewriting The Book of the Head Dictionary Contributor of the D&DL Department and erasing him from time, ______ became the new Head D.C., with the other Contributors none-the-wiser. They, however, remembered Miltontheus. (PROSE: {{esquivalience}} ^[+]Loading...{"page":"9-12, 16","1":"esquivalience (novel)","2":"'\"`UNIQ--nowiki-000001A8-QINU`\"'"})

After the Noodle Man was defeated, many individuals across the 10,000 Dawns and beyond awoke as if from a daze, and many of the events of the Noodle Incident were effectively undone, with York being largely restored, (PROSE: Taste the Noodles of Dracula ^[+]Loading...["Taste the Noodles of Dracula (short story)"]) following its destruction by thermonuclear missile. (PROSE: I'm So Normal I'm So Normal I'm So ^[+]Loading...["I'm So Normal I'm So Normal I'm So (short story)"]) To some, the events seemed to merely have been a dream, with some having a craving for pasta, while others such as Auteur, Lord Thymon, the Bookkeepers, and Marilyn Monroe retained full memory of the incident.

As reported by Sembla Belfort in issue two hundred and eighty-four of The Druimport Entwister, there remained traces of documents that were subject to facdocksparation. Academics gathered this evidence with their already mountainous collection relating to this phenomenon, leading them to conclude about the nature of what they named "Mnemosyne"; the perception of "replacements and amendments caused to time" was not limited to just time travellers and time sensitives as previously held, but to those not genetically predisposed nor deliberately protected. They also concluded that both physical and mental evidence were of the same ilk.

The Entwister further reported on Mnemosyne, giving confirmed examples of the phenomenon: the Monument To The Fallen Lorinians was recovered whilst the Lorinians themselves continued to thrive; a pair of bodies were found on Brighton Pier despite those individuals never had existed; and Rufus Wainwright's song "Between My Legs" included a reference to a city that had ceased to exist in 2371. The article continued on page nine. The newspaper itself, given its meta-temporal nature, was naturally Mnemosynic.

Behind the scenes

• As the ability is inextricably linked to time travel, direct or not, it was never brought up in the "classic" era of Doctor Who, as the show rarely showed the Doctor altering established history, let alone the effects of doing so. In one the ability's first appearances, Steven Moffat's 1996 short story Continuity Errors ^[+]Loading...["Continuity Errors (short story)"], it was regarded as a novelty.
  • Contrariwise to later media, an exchange between Steven and Vicki in The Time Meddler ^[+]Loading...["The Time Meddler (TV story)"] has the characters theorise that if the Monk altered the outcome of the Battle of Hastings, their memories would change so that they could only remember the new version of history. However, their theory is not proven, as the Monk was unsuccessful, nor did any character such as the Doctor confirm it.
    • The novelisation ^[+]Loading...{"noital":"1","1":"The Time Meddler (novelisation)","2":"The novelisation"}, while expanding the Doctor's explanation of the dangers inherent to the Monk's intereference, doesn't address their theory about memories.
  • Given that Continuity Errors ^[+]Loading...["Continuity Errors (short story)"] would influence many of Steven Moffat's scripts, the ability became particularly frequent in his scripts for Series 5 and Series 6. However, it became less frequent as the show progressed and stories with time travel integral to the plot diminished. It, however, did make an evident return in Russell T Davies's Season 1.
• Although rarely named in stories it appears in, the idea of individuals being able to recall memories of events in their lives that have been altered, of which they were not an active participant in the divergence, is frequent.
  • This ability is theoretically the same as the Mandela Effect, although most appearances of this concept are not identifed as the Mandela Effect, and many noted cases of the Mandela Effect in the DWU are actually of individuals, willingly or otherwise, forgetting historical events such as alien invasions. The Mandela Effect often has people remember one of at least two versions of history, whereas this concept has people remember both.
    • This is also applicable to déjà vu.
• The exact mechanics of this ability in the DWU often cary story to story, with some suggesting that only time travellers possess it, whilst many others show that ordinary people are at the very least able to subconsciously recognise alterations, manifesting in emotions such as sadness and fear.
• Oddly, Donna Noble is entirely unable to remember the version of history before she and the Fourteenth Doctor accidentally changed the name of gravity to mavity in Wild Blue Yonder ^[+]Loading...["Wild Blue Yonder (TV story)"], despite having been shown in Turn Left ^[+]Loading...["Turn Left (TV story)"] to be able to remember a parallel world that she negated.
  • Furthermore, the Tenth Doctor should be able to remember the version of history in Turn Left where he never met Donna.

Discussion in non-fiction

• The ability has been detailed in various works of non-fiction, often providing explanations for its mechanics.
  • The Absolutely everything we learned from Doctor Who this series... article in The Brilliant Book 2011 explains that this ability is caused by time travellers having their own complex histories which places them outside the "normal stream of events", immunising them from forgetting whatever was erased by the cracks in time. The article takes into consideration how things wiped from a time traveller's own history and how they then can forget it.
  • In the instalment of Who Knows! printed in Doctor Who Adventures #204, a reader asked how the Nestene Consciousness took a memory print of Rory Williams, who had been erased from time; the DWA team merely clarified the information seen on television, explaining that traces of Rory were deep inside Amy's mind.
    • This instalment was printed just two issues prior to Who Knows!'s replacment, Doctor, Doctor!, where the Eleventh Doctor would give in-character responses, so an explanation from his point of view was missed by a small margin.

Appearances in other non-DWU media

The ability to remember and perceive alterations to history has appeared in various series that have crossed over with the Doctor Who universe.

Wolverine remembers a previous version of history. (NOTCOVERED: House of M (part 3))

• In the Red Dwarf episodes Timeslides and Demons & Angels, Arnold Rimmer and Holly (in the former) and Dave Lister (in the latter) can remember previous versions of history.
• In the Marvel Multiverse, Bishop is shown to have this ability, such as in the Age of Apocalypse storyline, Wolverine in the House of M storyline, and Spider-Man in the One More Day storyline, among many other examples.
• In Star Trek: First Contact, the crew of the USS Enterprise (NCC-1701-E) can remember the timeline where the Borg assimilated Earth through extenuating circumstances.
  • Several Star Trek episodes from different series and various spin-off novels also feature this ability.
• In the Magic: The Gathering novel Time Streams, Karn remembers the averted timeline where a Phyrexian spy killed everyone at the Tolarian Academy, and planeswalker Urza can remember the broad strokes of the timeline despite having not time travelled himself.
• In The Crew of the Copper-Colored Cupids, some characters can almost remember Lethe-548 after her erasure from history by the Retconning Crocodiles.
• In the original, non-DWU version of the Faction Paradox audio story Eternal Escape ^[+]Loading...["Eternal Escape (audio story)"], the as-yet-unnamed character who would later become Dionus is aware that they keep forgetting the sources of the screams during the conflict as the people who made them no longer exist; this line of dialogue is altered significantly in the later version of the story.
