00:00Have you ever wondered what would happen if you couldn't sleep for days?
00:05In the 1940s, Soviet scientists decided to test the limits of the human body.
00:13They chose five prisoners and locked them in a room for 15 days with a gas that prevented them from sleeping.
00:21At first, everything seemed normal. But, over time, the prisoners began to behave strangely.
00:31On day 5, one of them started shouting for no reason and the others did not react.
00:38By the 10th, silence filled the room. The scientists, worried, decided to open the door.
00:46What they found was terrifying. The prisoners seemed barely conscious, but they resisted fiercely.
00:56They were shouting that they never wanted to sleep again. One of them murmured.
01:01We are the evil that has always been within you.
01:06The experiment was cancelled and all the information disappeared.
01:12Fact or rumor?
01:14Up to you.
