What is fantasy?

had a mind break for some time now; just about a brain dead phase and now, a bizarre question ringing in my head "what is fantasy?", some philosopher said that it is seperating beauty from ugliness or the gap between the two.. like seperating reality from the real? we create this strange reality, deluding ourselves so we can escape the real? whoa, I think that's the saddest part of human nature. The real has become the "horror" for us? are we living in a fantasy frame? umm, I sometimes wonder if that's what keeps us going. Just a rambling for the day.
