Out-of-Body Experience?

From elementary school to high school, I occasionally had experiences similar to an out-of-body experience. When I was about to fall asleep, even with my eyes closed, I could see the scenery in front of me, and it felt like someone was lifting me up from my back, getting closer to the ceiling or walls. Then, when I got scared thinking I would hit something and tried to stop, I would wake up. It wasn't a complete separation of consciousness from my body where I could see myself sleeping, but it happened a few times.
