@SaharaSon , sorry for what you go through with flashbacks.
I do the same, and a lot of people do.
Dissociation and dissociative experiences are common in PTSD, particularly during flashbacks. They don't necessarily indicate DID or DID-type behaviour.
I don't mean to be rude or otherwise, but there's a categorical difference between dissociation during a flashback, and even dissociation outside a flashback context, and then OSDD and then DID.
I think of it a bit like a spectrum.
At one end you have normal "zoning out", and things like highway hypnosis, then you have going on autopilot, going on autopilot under stress, going on autopilot under stress automatically, PTSD, OSDD and then DID.
It all sucks. But yeah, I guess the difference to me is dissociating whilst having a flashback and dissociating whilst washing the dishes and then finding some idiot has put your plates back all wrong and broken one or two.
One thing that I just wanted to add, is that a very strong theme that I have had throughout my life is abandonment, alienation and a profound sense of having been left behind. This theme runs hard through some of the movies like Platoon, The Deer Hunter and Black Hawk Down, and it hits me like a ton of bricks. When I was four years old I was abandoned by my mother, and she took my two older brothers from me as well. Nice. I was left with strangers in a strange land. To top it off my dad was severely injured. I was cut off of all communication. At a much later date we were reunited, but not before a h*ll of a lot of damage had been done. A psyche doc told me that in all probability, as a mechanism for coping with the trauma, my mother died to me emotionally at that time. Enter PTSD, CPTSD, IED, DID, and OCD? She f*cked me up pretty darn good. Talk about feeling like a motherless child...
