I noticed that a lot of the listeners have problems with nightmares. I myself have been plagued by them, what I finally found that put an end to my nightmares was star anise, it's a spice you can buy at any store.
I read that it would help to put it under your pillow or mattress. I put it in a thin cloth bag under my mattress and the result was immediate. No more nightmares, I also have a dreamcatcher in my bedroom and sage at the ready.
