Russian Sleep Experiment

The Russian Sleep Experiment is a creepypasta which tells the tale of 5 Soviet-era test subjects being exposed to an experimental sleep-inhibiting stimulant, and has become the basis of an urban legend.

[3][4] The story recounts an experiment set in 1947 at a covert Soviet test facility, where scientists gave political prisoners a stimulant gas that would prevent sleep for fifteen days.

It is considered by some to be the greatest and most shared creepypasta story ever made and Dread Central's Josh Millican has called it "one of the most shocking and impactful urban legends of the Internet Age".

[5] In the chapter "Horror Memes and Digital Culture" in The Palgrave Handbook of Contemporary Gothic, Tosha R. Taylor wrote that the creepypasta "reflects residual political anxieties as it purports to reveal a top-secret effort by Russian scientists in World War II.

[14] Several other adaptations have been created, including a film based on the short story entitled The Soviet Sleep Experiment, with Chris Kattan starring and Barry Andersson directing.
