I have a lot more nightmares than I used to. It appears they are caused by being uncomfortable when I sleep. The RSD mostly shuts down when asleep for me so nightmares aren't a big problem. Every morning almost, shortly before I get up I have what I think of as an RSD nightmare but it's really part of the post traumatic stress syndrome probably. I'm always at a job I can't do because of my condition but there's no real expectation that I do it. I knock myself out anyway in most of these dreams. They aren't true nightmares since they aren't really frightening. They are terrible dreams.
