I used to mainly have nightmares that were exact recurring events that I experienced during 27 years in the military. There are many of them, so there was a good supply and they were also the things that could consume me or get triggered out of the blue during the day. Lately, over the last year, my nightmares have changed. I'm now dreaming of things that never happened: the people are all wrong, the places are wrong, the situations are drastically impossible, but they are in fact spinoffs/worst-case/extreme scenarios of what already bad real experiences could have been. The physical result of them is very similar to the recurring nightmares in that I wake and cant go back to sleep, but what exactly I was dreaming usually slips away into obscurity in my mind quickly. Anybody else experience these?
