The exact same thing happens to me. I've never been able to put it into words the way you have. The fact that you have the same experience as me scares me even more, makes me feel as though it is not just my imagination playing tricks on me to have someone see or feel the same things that I do. Waking up in a dream, not being able to move, hearing this powerful loud yelling demonic voice yelling and having total fear come over me and then waking up in the same position I was while I was in the dream. The way I can relate terrifies me
