This happened when I was between 10 and 11 (and since I've told this story to other people and they always ask, I will confirm now that I was NOT on drugs, I was a little kid). I believe what happened to me was an out of body experience.
I had spent the night at my friend's house, it was small with an L shaped stairwell by the front door (it had about 3 steps until you reached the landing and then the stairs continued to the right all the way up to the 2nd floor).
We woke up that morning and decided to go down stairs to watch TV (I felt kind of disconnected at the time), I sat in the rocking chair that was at the bottom of the stairs (you could see up to the landing from there).
As I was sitting there, I was suddenly LOOKING at myself sitting in the rocking chair; the position I was in to be looking at myself was up high, near the corner of the ceiling on the landing of the stairs.
I remember thinking "WHAT?" and then I was back to myself in probably less than a second. It felt like the wind was knocked out of me when I came back and I just sat there kind of gasping for a minute trying to wrap my child's mind around what just happened to me.
When I was about 17, I bought a book about psychic things and realized what had happened to me was an OBE.
The weird thing is, once it happened, the disconnected feeling I had that morning continued for a couple of years afterward but stronger and randomly. I'd like to explain it and see if anyone else has experienced what I'm talking about because it was a HUGE issue for me when I was younger, it really scared me and I never told anybody.
My parents were about to divorce etc. And maybe the disconnection was a way for me to try and block it out?
I'm not sure, but I felt as though I was literally being pulled away from my physical body ALL THE TIME. I would get a really, really tired feeling (even though I wasn't) and then a pulling sensation like my soul was trying to float up and out. I would try SO hard to fight it to 'stay' in my body; the worst one happened while I was in the middle of playing Mario cart racing with my friends in the middle of the afternoon, I felt as though a vacuum were on me sucking me away from everything, the TV screen got weird, I couldn't see it clearly, I started to black out I couldn't concentrate on anything, almost like I was falling into a DEEP sleep against my will, and then the pulling sensation; it was so strong I honestly thought I was going to be sucked from my body, die and never come back. I had to quit the game to go outside. I think either, I was going through a rough patch in life mentally, or I was very close to having OBE's against my will because it was always same exact feeling as the first time it happened. Luckily, the feeling hasn't happened for a couple years. After I bought that book on psychic experiences though, I tried to re-create my OBE with no luck, but I think I did actually manage to do something weird. I won't explain that though because I'll sound insane
Your experience sounds a lot like an OBE, and I agree with Rook's diagnosis.
Unlike you, I've never had an OBE while I was awake, although they have happened a lot in a dream state. People say that you cannot die in dreams, but I once had a dream during which I was killed, and then my spirit separated from my body; I had an awful fright when I looked down and saw myself dead! I woke up feeling as I did in the dream: sick and disoriented. Anyway, just sharing my own experience with you guys ^^
Do you have OBEs in a dream state as well? I'd be surprised if you didn't;)
