First a little background: I have had regular nightmares since early childhood. I often wake up 2-4 times in middle of the night because of the dreams. Not monster-in-the-closet nightmare, but just about any "normal" dream you can imagine that causes regret, fear, dread, or sometimes even just sorrow. Sometimes the dreams are "good", but then they always end bitterly to remind me of some regret or loss.
Now, I've just read The Power of Now for the second time. I believe the dreams are caused by the Mind. The dreams are always relevant to my current life situation, topical to my current fears and regrets. Perhaps the dreams are a manifestation of my pain body.
I can't become present when I'm on the edge of sleep. Whenever I watch the Mind, it wakes me up further. I can relax somewhat while feel my body, but when I do that, the Mind just starts up anyway, if I catch it, I have to watch it but then I'm back at waking myself up.
How do stop it? My sanity rests on this.
