Hello Rainbowboy: I see this is your first post here on PC. So... welcome to Psych Central.

I'm sorry you are struggling with these difficult dreams. I think it's great you were able to discuss them with your dad! I know you wrote you haven't talked with your mental health professionals about your dreams. And I can understand your concern. But if these dreams continue to occur, this may be something you will want to discuss with your therapist if you're seeing one. In the meantime, perhaps writing about it here on PC will be of some help. Here's a link to an article, from Psych Central's archives, that outlines a technique for eliminating recurring nightmares:

I hope you find PC to be of benefit.
