Cover art for The Trial lyrics by Pink Floyd

JesseDC : interesting opinion that the wall is a bit like The Matrix. I think this song means that Pink is so screwed up by the life he has led. Be it from drugs, stress his upbringing(parents, teachers, and girlfriends. That he is forced to confront his demons. and only then can he be free to be who he is.
