I have many in that the same trauma was often repeated and became cumulative: abuse and neglect from my mom and dad (respectively) since I can remember, and I keep remembering earlier incidents with mom; serial harassment, humiliation, property crimes and beatings (the incidents were often daily and probably three times a week on average) from the other kids at school, and teachers would often join in the humiliation, second through twelfth grade; emotional and physical abuse from a teacher who was fired for abusing his entire fifth grade class; one sexual molestation by a stranger when I was a very innocent 15 year old, a gang rape at age 18 and several subsequent "date" rapes; a one-year, classic, quickly escalating domestic violence live-in relationship where eventually I was going to work with visible bruises on my arms, and had been strangled more than once. During this scene there was much humiliation, verbal and sexual abuse, and another rape.
I believe there are things from my past which I still do not remember. Many of my childhood abuse incidents were shrouded in amnesia until this year (I am 40).
There was only one, one-time trauma: I was witness and first to the scene of a fatal car accident when I was 29. The poor old woman was so obviously and horribly dead, I realized not only would CPR do no good, I was not capable of it, froze up and became numb immediately. I was debriefed the next day thanks to knowledgeable co-workers. I feel that I dealt with that trauma adequately and though the image haunted me for quite a while, the accident was eventually integrated into my adult life experience as well as anything like that can be.
