Benyam Mohammad, an Ethiopian-born Guantánamo detainee who grew up in Britain, said he was held at the “dark prison” in 2004 and described his experience to his attorney in English:

It was pitch black no lights on in the rooms for most of the time.... They hung me up. I was allowed a few hours of sleep on the second day, then hung up again, this time for two days. My legs had swollen. My wrists and hands had gone numb.... There was loud music, [Eminem’s] “Slim Shady” and Dr. Dre for 20 days.... [Then] they changed the sounds to horrible ghost laughter and Halloween sounds. [At one point, I was] chained to the rails for a fortnight.... The CIA worked on people, including me, day and night.... Plenty lost their minds. I could hear people knocking their heads against the walls and the doors, screaming their heads off.
