I didn't know where to post this, so sorry if it's in the wrong section.

I used to have this experience when falling asleep as a child. I haven't had it again since I was maybe 8 or 9. I would go to bed, and after trying to go to sleep for a while I would have this weird experience where whatever I focused on would seem much closer to me than it really was. For example, I remember looking at my bedroom door, usually it was on the other side of the room, it would instead be right in front of my face. What I was seeing was usually quite fuzzy as well, and it was not static, it seemed to always be coming closer, although never really moving too much. It was also accompanied by a feeling of fear. I hated it, it was like the room was closing in on me.

It's hard to describe it any better than that. I've always wondered what it was, so I thought I'd ask. I'm not sure if it was SP, because I don't remember being unable to move, or any vibrations. Please share if you have had this experience before, because even though it frightened me, there was something beautiful about it, and I'd love to hear your thoughts.
