In one sense, of course, we always have bodies while dreaming. The dead, that is, those who no longer have physical bodies, I presume do not dream. It might be a question for those who believe in soul-sleep, "do soul-sleepers dream?"
But you specifically asked if I have a body in my dreams. I seldom dream nowadays, but did when a lot younger. In some dreams, as I recall, I did not seem to have a body, or at least I was unaware of one. In those dreams I seemed to be a bodiless observer of some odd events. In other dreams I distinctly remember having a body and participating in whatever activity I was dreaming about. However, I consider dreams in the same sense as illusions, the result of a free-running memory system when conscious (waking) control is removed, of which we become aware during that semi-conscious state when just going to sleep or just waking up. Otherwise, they have no significance whatsoever.
