Toward the end of the 1940s, Soviet researchers sealed five prison inmates in an airtight chamber and dosed them with an experimental stimulant gas to test the effects of prolonged sleep deprivation. Their behavior was observed via two-way mirrors and their conversations monitored electronically. They had been promised their freedom if they could go entirely without sleep for 30 days.
The first few days of the experiment passed uneventfully. By the fifth day, however, the subjects began showing signs of stress and were overheard bemoaning their circumstances. They stopped conversing with their fellow inmates, choosing instead to whisper compromising information about one another into the microphones, apparently in an effort to win the favor of the researchers.
Paranoia set in.
On the ninth day the screaming began.
