What if you start giving yourself a message every night before sleep, that whatever you dream is just a dream. See if it changes how you think when you wake.

I've had dreams where I wake up and tell myself whatever is in the dream is not real. I'll go back to sleep and tell what/whoever is in the dream, you're not real, go away. and they go away in my dream. Have been able to do this for about 7 years now.
