A description of the experience
Menachem Begin, - White Nights: The Story of a Prisoner in Russia
In the head of the interrogated prisoner, a haze begins to form. His spirit is wearied to death, his legs are unsteady, and he has one sole desire: to sleep... Anyone who has experienced this desire knows that not even hunger and thirst are comparable with it.
I came across prisoners who signed what they were ordered to sign, only to get what the interrogator promised them.
He did not promise them their liberty; he did not promise them food to sate themselves. He promised them - if they signed - uninterrupted sleep! And, having signed, there was nothing in the world that could move them to risk again such nights and such days."
