I think you might be experiencing somnambulism (sleep walking). This has happened to me a few times and it felt just like you described. Your sub conscious mind is controlling you when this happens. What I think is happening is you are about to have a OBE whether it be conscious or unconscious but the body is not relaxed enough so it gets up and does random things instead of the astral body. Does that sound about right?
I forgot to post this. A week or 2 ago, i thought my alarm clock went off, but it didnt. I was awoken from it and the time said 3:00am. But, the strange thing is, that i woke up again and the time said 3:30am and my head was on the head rest thing behind my bed, and my light was on. Noones in my house but me. I never put my head on the head rest and when i do wake up in the morning at 6:30 i fall right back asleep, not put my head on the head rest and try to wake up. Was this an astral projection or obe? I was in full conciousness and thinking to myself, why am i up right now, its on 330 in the morning im going back to bed. But the thing was that my room was dimmer with the light on, so i just turned it off and went right back to sleep, thinking i just turned my light on thinking i had to wake up. For now on i think im going to hop out of bed when ever i wake up, just incase something like this
happens again. And one more thing happened back in the summer, i wanted to turn the tv on, but how stupid was i once again? The remote control was under a dresser when i slept over a freidns house, i never touched it at all but i woke up 3 times to the tv going on. Could that have been a begingin to an obe?
Now you COULD jump off a building, but.... youd die.
