Sometimes I dream that I was flying. Mostly it is like jumping and when my feet leave the ground, I seem to be floating. It's a nice feeling that when I wake up, I would close my eyes and savor that dream of flying for some more seconds. One friend who is into occult said that when dream that you are flying means your spirit is leaving your body. And you can feel your spirit levitating but since your mind couldn't comprehend so your mind invents something that you can understand, that is floating on air or flying.
