OK this may be a strange tip but its worked for me and maybe it can help someone else:
I leave the TV with the volume set so I can just barely make out the voices. I leave it tuned to a channel that has innocuous content and then go to sleep. Somehow the voices seem to penetrate into my sleeping brain and sidetrack the nightmares. Rather than dreaming I'm trapped in a mass grave I'll end up dreaming about how to make a patio or the "History of Sugar".
