PTSD will do that.
In 1997, my most recent PTSD trigger was watching the death of two biker friends who were run down by a drunk.
For many years, and still, somewhat to this day, I wake up crying.
Since my mind apparently blocked out all conscious memory of the accident, I have to assume that I dream about it, often.
I also see things while awake that trigger it, such as dust flying off the road *just the right way*, because that was something I “saw” when it happened.
I wish I had an answer for you.
They tried hypnosis on me but I’m one of those trust-no-one types it won’t work on.
Oh my. Sorry that happened. I can’t imagine bow traumatic that must have been.
Hypnosis probably wouldn’t work for me either because I’m the same way about trusting people.
