I know already what will happen: somebody'll drag me out of the fog and we'll be back on the ward and there won't be a sign of what went on tonight and if I was fool enough to try and tell anybody about it they'd say, Idiot, you just had a nightmare; things as crazy as a big machine room down in the bowels of a dam where people get cut up by robot workers don't exist. But if they don’t exist, how can a man see them?
