Blind Demons
He was in a complete blur of pain, effectively blind and helpless. He could see the difference between light and dark but nothing else; it was all a throbbing, out of focus blur of incredible pain. Every so often they would shoot him up with morphine or Demerol or whatever they were shooting him up with and the nightmare would turn into a blurred cartoon of a nightmare until it wore off and he was screaming with pain again.
