One thing someone suggested to me that REALLY helped this problem [nightmares] was this: praying OUT LOUD and anointing my pillow, headboard and bed with oil before I went to sleep at night. I anointed it with oil and prayed the Lord's protection over my bed, my nighttime and dreams as well. (I am a very avid dreamer.... and GOd speaks to me very often thru dreams. It is because of this that I think SAtan attacks me harder than others, in the night... trying to 'scare me' out of my dreams.....).

GOd ordained sleep for us weak humans... it is of Him. Of course the enemy of our souls would want to mangle that anyway that he can.
