In some of what I think are dreams, I'm aware of everything thats going on in the room but my body is frozen. I tell myself over and over to wake up or move somehow and I often can't. Which panic sets in! In over half of these episodes that I've had I have often seen silhouettes walking towards me or even trying to pull me off the bed. I can't make sense of any of them. If someone would care to explain it would be most appreciated. TY
