I've had maybe three of these weird experiences in the last 6 months. I'm dreaming away happily, deeply asleep, when I'm woken up by what feels ridiculously real. It feels like someone has a hand on either shoulder and is pushing down hard a few times. Both times this has jerked me out of sleep and frightened the hell out of me. I feel like I bounce back off the bed with each shove and then after a few seconds it is over. There has never been anyone else in the room when I look around. I was wondering if anyone else has had a similar experience? I'm at complete loss as to what it could be.
