I had this encounter/nightmare (?) about two years ago. But unlike most nightmares, I can remember this one vividly.

I was asleep and lying in bed. I think I had cracked my eyes open to see whether it was bright out yet. It was maybe about 4, 5 or 6 in the morning. I then felt something jumping on my bed and could actually feel my weight shifting as it jumped. I couldn't see it as it was invisible. This thing than jumped on top of me face down. Whatever it was, it couldn't have been large because it wasn't crushing my whole body, but I could definitely feel its weight. Its face was very close to mine, (maybe an inch) and I could feel its breath on my mouth and nose. This scared the hell out of me, and I tried to move but was completely paralyzed. I couldn't even yell out for help. This lasted for about 5 seconds. Than suddenly, the paralysis lifted and the thing on top of me was gone.

This event seems to coincide with the symptoms of sleep paralysis. But, is it REALLY a disorder or something........else? Can someone give me a NON-medical explanation for what happened? Before I come to a definitive conclusion, I want to consider the supernatural explanation...

Just so you know...I NEVER have nightmares. Especially not ones like this. I havn't had another one (that I can remeber) since this event. Maybe I'm just making much to do of nothing........But this nightmare ( or whatever it was) has always been at the back of my head, nagging me. I just want some closure.
