Nightmares keep me from ever wanting to sleep again and I do not dream about the trauma, but I dream about how I felt during the trauma and create my own scenario somehow when I am a sleep. For instance, my head was held under water as a child as a form of punishment, I do not dream about this happening very much, but I dream of sinking in the ocean in a great storm, or being swept down river of a flood that has taken out cities. They are very vivid and very real, that sometimes when I wake up screaming, I can swear I taste salt water from the ocean, or mud from the flood I was in.....very scary stuff. My dreams are all reoccurring, I have had some of the same dreams for over 25 y ears. Sometimes I acknowledge I am dreaming in my dream, I feel trapped and know I can't wake up until I have completed the whole dream.....weird, but true. I think your dreams are related to PTSD
