Time helps me. I had a couple intense/bad dreams that I still think about today, I remind myself they were dreams, that what they depicted has not happened or has happened in the past, is not happening now.
Sounds like you are dealing with post traumatic stress dreams and that could be good/helpful to you in your waking life:

I remember when I use to have continuous anxiety dreams every night in my late 20's/30's but then I realized having such chaotic dreams helped me be more "together" and function during the day.
Finding caring friends and loved ones helped me too, and my sense of humor. . .
