answer:Yes, I’ve experienced it, and I believe that sleep paralysis is responsible for many so-called “paranormal” experiences. For me, it feels like a half-asleep half-awake state where the dream is still going on, but it’s tapering off and so I may still hear things, see things, or feel things from the dream and I can’t move. In the middle ages, people used to think the feeling of heaviness on the chest caused by paralysis was caused by a demon sitting on their chest. 10 minutes is a little strange, though. For me, it’s usually no more than a few seconds that I “wake up” and I can move and any sound or feeling that I just experienced is gone. It’s a very odd and creepy phenomenon.
