Katrin Büchel, Karl Heinz Bomberg, Siegmar Faust, and Thomas Hannemann were imprisoned and interned for weeks and years in the GDR on charges of “subversive agitation,” “attempted defection,” or “difficulty in discipline.” In SPLITTER IM KOPF, they give a powerful account of the methods of physical and psychological repression, the feelings of vulnerability, and the consequences – which include depression, claustrophobia, mistrust, and psychosomatic disorders.
