The Russian Sleep Experiment

  1. Bermudez says she believes the scariest creepypastas are the ones that blur realism and internet folklore, like The Russian Sleep Experiment, which taps into body horror and unethical science.[3] The Russian Sleep Experiment” is a fictional experiment that, according to legend, occurred in 1947, when Soviet scientists placed 5 inmates in a gas chamber. They promised to let them out after a 30-day experiment, in which the gas was supposed to prevent them from falling asleep. Throughout the course of the experiment, the inmates descended into insanity, turning into violent, zombie-like creatures who eventually died.[4]
    • Why it’s so scary: The eerie, vintage-looking visuals add a touch of reality to the story, making it look like an experiment that could have truly happened. The graphic depictions of self-mutilation and self-cannibalism are horrifying enough to disturb even those with the strongest stomachs.
