So what about 'emotional flashbacks'? They're dissociative in nature; that IS the flashback. I do think there is a relevant difference between PTSD-based flashbacks and childhood traumatic flashbacks / emotional flashbacks. However, I've never heard of flashbacks stemming from neutral or positive events in life. I think most people would call that a memory. To me, that's the problem. Dissociative flashbacks are pathological in nature; memories aren't. If this is true, then isn't it likely that dissociation is the difference between a memory and a flashback?
I differ from Amandalouise - I use my own research as part of the therapy. Sometimes it affects me, sometimes not. But that's just all grist for the mill....Everyone follows their own muse.
