My accident was a horseback riding fall. None of these nightmares have been about horses though. They have been more violent type nightmares like someone is chasing me. I do have a therapist (psychologist), but we haven't figured out why this is happening other than it is another symptom of the concussion.

I haven't really thought about anger as a reason for the nightmares, but it could be. I'll have to think about that more.
