It may very well be able to. After learning to fly and what not in the "dream world", sometime I wonder if I "truly" believed it, I would be able to do the same thing here. I don't know as there is to much "doubt" when I'm in the "real world."

But I got to say "doing stuff" in dreams while perhaps is enjoyable, it is nothing like the real thing. In dreams it is all about one's self satisfaction, for it's just one party involved with their own fantasy/fantasies. While the real thing is two individuals joining together becoming one for a moment in time. This is very much underplayed in pop culture and media but it is certainly a very real occurrence, and no dream could ever compare with it.
