Invasion via dreams

In 2010, the Nightmare Man invaded the dreams of Luke Smith, Clyde Langer and Rani Chandra, turning them into nightmares, and planned to do the same to the rest of the world. Luke had several nightmares in which his friends didn't care that he was leaving for Oxford University. Rani dreamed she was on the BBC News studio being convinced by Louise Marlowe to tell everything she knows about Sarah Jane Smith. Clyde dreamed he was working in a burger bar (instead of as an artist) and being taunted by an elderly Sarah Jane. The Nightmare Man was defeated when the three used their bond to overcome their fear and trapped him in the dream dimension, in which he was tormented by the elderly Sarah Jane, telling him how wonderful Luke was. (SJA: The Nightmare Man)

In 2050, the Bodach caused all of London to fall asleep and dream. Starkey dreamed of chased by a Jixen in a strange place and running into Jorjie Turner and Darius Pike who sneaked behind a Obelisk, he was terrified as he spotted a Bodach avatar moving behind them. When Starkey woke up he fled from a Jixen in his bedroom, when he found K9 Mark 2 he told him to shot the Jixen. However, the alien threat K9 detected was Starkey and he terminated him, Starkey woke up after he was shot.

Darius Pike dreamed of being trapped in his car Mariah, surrounded by clowns who joined him in the car. In the waking world, when K9 discovered him shouting for help and to be let out, he observed Darius' behaviour as "strange" and remarked "this one's going in the memory banks". Alistair Gryffen dreamed of the day he lost his family.

Jorjie went into June's nightmare in the Bodach's world with a fake love tattoo, distracting the furious June so Jorjie could pinch her, thus waking her up and freeing her from the Bodach's control. This allowed her to remove an Eye of Oblivion in the Bodach obelisk so K9 could destroy it. (K9TV: Dream-Eaters)

Behind the Scenes

Occasionally the writers of authorised DWU media have used the Doctor's dreams to either retcon iffy but canonical situations, such as the Eigth Doctor's dreams of John and Gilliam in The Land of Happy Endings or to give non-canonical events some DWU traction, as in the Seventh Doctor's dreams of the events of Dimensions in Time.
