"Sleep No More" is the ninth episode of the ninth series of the British science fiction television series Doctor Who. It was first broadcast on BBC One on 14 November 2015.^[2] It marked the first time an episode of the series had not featured any opening titles - the title and writer were instead announced at the beginning of the end credits.

The episode is a found footage video engineered and narrated by Gagan Rassmussen (Reece Shearsmith), a crew member of a space station orbiting Neptune in the 38th century. In the episode, Rassmussen manufactures a perilous adventure involving Sandmen—humanoid creatures made of rheum—to make more people watch the video and allowing the spread of an electronic signal to other people's brains that will create more Sandmen.
