High-value prisoners were kept in absolute isolation for more than a decade. “We were beginning to think we were dead, that our cells weren’t cells but rather graves, that the outside world didn’t exist, that the sun was a myth,” one of these prisoners, Mauricio Rosencof, recalled. He saw the sun for a total of eight hours over eleven and a half years. So deprived were his senses during this time that he “forgot colors—there were no colors.”
