I had a very rough childhood (parental abuse and bullying at school and by teachers) and seem to remember a few of those instances quite clearly, almost like PTSD. Yes there were some instances where my parents (mainly) would beat me so badly I could not stand anymore and was afraid for my life and did not know how to escape. Those are the ones I remember most clearly and have described these in a story to try to accept and get over them. Yes I would go in shock in remembering one in particular and would have to snap myself out of it, try to remain conscious of what was happening, and retrain myself to think of it differently. Then there are some "milder" memories of traumatic experiences. I always thought it was because I have an exceptionally good memory so I would remember the greatest details (until I took psych.) Sometimes these memories seem to come back for no reason. So I seem to have a (yet to be named) milder traumatic disorder and PTSD. This has gone down gradually over the years I worked on it. This is something i was not diagnosed with officially and have worked on my own to get over.
The way the brain works is that stressful events and trauma (especially, but still amongst other things) will be engraved in memory, sometimes to the detriment of someone's psychological health. I guess for those aspies that are "gifted" with an excellent memory it is worse and encompasses far more than it would for NTs, at least on the trauma side and could be easier to engrave to form PTSD and then the anxiety and distress may be greater in AS. But research would need to be done to conclude that, it would still be interesting to look at. It is true that also being an aspie, we are clearly different and bullied for it, which may increase the incidence of traumatic experiences. My brain also sometimes makes events more traumatic. Especially when I do something embarrassing I will remember it for a while even if no one ever mentions it or saw me. I agree however that perhaps this thread should be retitled AS and the formation of psychological trauma.
Little note on ketamine, really cool that someone mentioned it but interestingly in high levels in can lead to pseudo-(because it was induced)-psychotic symptoms.
