The subject was tied down by four points and also across the waist and neck. They were then wrapped in a cocoon like manner with soft gauze to limit movement or any feeling or sensation in the limbs. Usually, "subjects" were fed intravenously and then underwent severe sensory deprivation, broken by bombardment with extremely loud noises. A darkened room would be broken by glaring white lights in the middle of the night, and the "subject" loses orientation of night or day.
The subject, when near breaking, is then shocked heavily and drugged. They may be placed temporarily on a respirator, and given paralytic drugs. The anxiety level reaches extreme points as this abuse continues, and I had heard of people literally having a heart attack from fear at this point. The person is drugged and shocked again, and then told that they are dying. They watch their body from above, and are actually glad that finally release will come from the days of torment at this place.
