I have had those kinds of flash backs n I have had dissociation at times but I do not relate the flashbacks to the dissociation - rather I think the image of me I am seeing is the image my brain remembers as being me at that age n since I am no longer there I AM an observer - not a participant. Much like when you go back in your memories with your therapist into a traumatic memory .. the therapist may remind you that you are no longer at that place but rather just observing the memory if he or she notices you becoming too aggitated.
