Several posts were being written as I was composing, so now I think I have a clearer sense of the ideas here.

I like the Schore quote. TBH I've never been comfortable with the term "flashback." I'm not even entirely sure that it originated in the professional literature, or if it migrated from popular usage in the 70's into the profession. I experienced what is commonly called "flashbacks," but they just weren't so clearly confined to a single past moment. I didn't have many such events, but they weren't clearly narrative memories, nor sense impressions ( or conditioned sensorimotor traumatic responses, in Schore's terms). They were a mix, a jumble, more than reflective of a discrete event. The "stuff" of them was clearly of the past, but which part would date to which event at which age would be difficult, if not impossible, to determine. And I have no reason to believe any such determination would have necessarily been objectively provable. For me, what was more important therapeutically was maintaining stability in the face of them, and the subjective emotional truth to be discovered through them.
