Natural remedy for nightmares?

I'm having a problem at the moment with nightmares. I constantly wake up in the night and don;t have much trouble falling back asleep but the next day it really affects my mood, I feel really down and low, and I just feel like crap because my sleep was disturbed.

They are not scary nightmares, more stressful and they usually involve me being really angry and stressed with someone.

I don't really want to take any more medications so does anyone know a good natural remedy that might help this?

i was a severe sufferer, was on ergadryl, in dark black rooms for days on end. warm water flowing at the base of the neck (nape), do it in the shower with your head slightly forward. also allow water to run off your head, stay right under the stream for a good few minutes. a nice dark room really helps. have fluids as well. water. people who suffer migrains get dehydrated. some people get migraines due to dehydration. healing thoughts i send. i fully understand. hope this helps a little.
