Well, first of all I have to say that I think you had a false awakening with dream components to it. I first thought "autoscopy" which is a brain phenomenon, but it would only apply if you can physically see where you were from your bed. So chances are it's a dream. For more info on how the theories on how this works read Robert's treatise, which I'll link to you. Treatise on astral projection: http://www.astraldynamics.com/tutorials/?BoardID=65 As for reality, I think the question is objective or subjective. Reality can and usually is a bit of both, and it's the same in AP. Just run a search on 'reality' and you'll find all kinds of theories and ideas on it in the forum.
