Its so funny. . . my first big Out of Body / astral experience was like the other side of what you experienced. Years ago, in my grandparents house in Havana Illinois, I kept getting pulled out of my body and drifting towards the laundry room. Everything looked exactly the same . . . I could read the book titles on the shelves. I could distinguish the wallpaper patterns.The colors seemed a little off but it was still the same house. . . . but instead of a laundry room, I found a girl, sleeping in her bed. At that point, I thought "Well this doesn't belong. It MUST be a lucid dream" and so I went to touch the girl but as I did so, she bolted upright, looking terrified. She was looking around the room, unable to see me but clearly felt my presence. That freaked the shit out of me and I felt bad about it. . . .I instantly snapped into my body and have forever wondered if that girl was somehow real or dream. This was back in like 1992 or so.
