I find it weird that I don't overtly identify as having PTSD nightmares. Maybe I do and I'm just naming them wrong?
I did not classify my dreams as PTSD but I have since come to believe they were just that.
My dreams were heinous, but I was used to them. Sometime they "carried over" a feeling throughout the day, but usually I remembered them but I was fine after waking up.
I think the key was I had BAD dreams and virtually never an inane or pleasant dream. Some of these dreams were repeats that I had for decades.
My dreams varied but the themes always centered on fear, physical pain and either running from something, physical battles and witnessing a lot of torture. They were ugly. Close friends used to joke I needed to write horror novels.
I did think these dreams were my peculiar way of sorting things out, and they probably stemmed from my childhood but they didn't really bother me. Well, until the daytime flashbacks started, LOL
Later after some therapy my dreams started "changing".
For example, I had some where the theme was not so bad, but they disturbed me like I kept dreaming about a shirt I had as a kid. I didn't remember until the dream it had been so long ago. After awhile these started to fill in the blanks on missing memories. Today I absolutely know why the shirt was important to me. The dreams began bothering me more during the day, leaving me feeling uneasy and nauseous sometimes. I did have bouts of insomnia and then my PTSD really flared.
In conclusion I did not consider these PTSD but given the fact my 40+ years of multiple nightly heinous dreams is now maybe a bad dream every few weeks. Yea, I would say they were PTSD trauma dreams.
This sounds strange but I had such an active dream life...I joked I had 2 lives going on. I sort of miss the dreams, its hard to explain. But I still find if something is bothering me, my dreams pick up in frequency/content. It helps me realize now I am under stress or need to deal with something.
Hope something helps,
