The Russian Sleep Experiment is a creepypasta which tells the tale of 5 test subjects being exposed to an experimental sleep-inhibiting stimulant in a Soviet-era scientific experiment, which has become the basis of an urban legend. Many news organizations, including Snopes, News.com.au, and LiveAbout, trace the story's origins to a website, now known as the Creepypasta Wiki, being posted on August 10, 2010, by a user named OrangeSoda, whose real name is unknown.
