I actually have had this kind of dream before.

Whenever it happened, I was unable to move at all or control my actions.
What I did later on after I got better at dream battle, was use the moment the communication began by devouring the information exchanging on both sides. If you are talking, someone is recieving.
Using that as a starting point would go ahead and take information from the other side and slowly regain movement and when it was enough, fight my way to wake up at the beggining and finally to confront and eat away at the ones stalking me.
