A weird dream I had

My wife's alarm jolted me awake from a dream I've never had before..

in which I was living in someone else. I didn't see a mirror, or water, or anything, to see my appearance, but I was walking around, and being someone else, entirely, a kind of virtual reality that was completely real to me, and which I became surprised to exit upon re-entering everyday me. I was in my head, my virtual and dream-head, and was enjoying myself, although it was a pretty normal type of circumstance, as dreams go. I was thinking in my head as if was awake.

I know this is supposed to make me go:
-hmm, is everyday life only a dream, too.
-Does this other me dream of my life when He goes to sleep?
-Is this heaven, or some circle thereof?
-Can this consciousness outlast my life, and therefore be an afterlife (if only in a computer, or whatever)?
-Was this dream self-generated, or put in my head by some morpheus kind of person?
-Does it matter what I believe in response to this dream?

I enjoyed it, and I hope for more.
And if I'm in a coma, this may be happening to me, so I don't want my plug pulled.
