From my experience, my nightmares are directly linked to PAIN! Usually, I have my leg in the jaws of a large crocodile, or I am being crushed by some type of large machinery. Maybe my foot is in a campfire... you get the idea.

I have a mild sleeping aid (Ambien) that I take if I am having a particulary bad evening with a lot of pain just before bed. Maybe that would help. Just don't overdo it. That stuff can be a bad mix with heavy-duty pain drugs!

Hope you get some good rest soon.
