I would start by trying to figure out what they are trying to say to you....unless you can tie them back to some movie or TV show or something you read in a book, it might be your subconscious warning you about a danger you see in your life.

Sometimes after we figure things out, they will actually go away.

Otherwise, like with me, the nightmares that hit after a trauma I went through....nothing controlled the nightmares except for seroquel......but that was because of a specifit tramatic event in my likfe.
