Ghost

For the audio drama, see Ghosts (audio).

Ghosts are a phenomenon occurring in the collective mythology and popular culture of Earth and other worlds including, perhaps, Skaro. Those who believe in ghosts sometimes hold them to be souls that could not find rest after death, and so linger on in the world of the living. This inability to find rest is often explained as unfinished business.

Doctor Who

A ghost is sometimes referred to as a fetch, and the woods around Fetch Priory were long believed to be haunted, the result of its being near a relative continual displacement zone or hole in time leaking images and other phenomena from light years away (DW: Image of the Fendahl)

The Ninth Doctor later matched this explanation while fighting the Gelfh (DW: The Unquiet Dead)

The Doctor explained that Psychic residue was a cause of ghost sightings. (DW: The Pandorica Opens)

Torchwood

[[Quantum tr

Eugene Jones was able to interact with Gwen Cooper of Torchwood Three for a time after his death as a de facto ghost. Ultimately, he briefly became visible to not only Cooper, but other members of the Torchwood team, before "crossing over" and ceasing to be a ghost. This was due to his consumption of a Dogon Sixth Eye beforehand granting him a new perspective on life. He would eventually unlock the secret to true peace and happiness allowing him to let go of his past life and surrender to Death's advances, effectively ceasing to exist in the process (TW: Random Shoes)

A Cardiff building was haunted by three cowled men with scythes, it is unknown what these things actually are, but they were considered ghosts. [{Toshiko Sato]] and Ianto Jones were sent by Torchwood Three to kill them. They appeared in front of them, and were shot dead by Tosh and Ianto. They were merely "shadows" cast by The Rift. (TW: Exit Wounds)

The Sarah Jane Adventures

Professor Alistair Gryffen's numerous failed attempts to retrieve his family with The Space-Time Manipulator warped reality into the shapes of his wife and children. They functioned as ghosts but needed to trade places with Jorjie and Darius so they could take physical form. They were ultimately banished back into nothingness. (K9TV: The Fall of the House of Gryffen)
