In the past 6 months I've been experiencing a very strange phenomena(sp?). Sometimes when I close my eyes and relax completely, I lose sense of my body completely, and a perfect picture comes into my head of someplace ive been. In this state of sleep, I never see any living creatures but I can usually look around and its a picture perfect image. There is nothing surreal about the area, basically like a photograph but with bad color, and it doesn't use up my full vision but instead actually looks like a photo in my mind. Does anyone else experience this? What is it exactly?
