I had the experience of a pre-verbal traumatic re-experiencing and was very surprised that it was happening. I had no access to any memories at all, couldn't even guess the context or situation. When I expressed frustration about not being able to work on it because I couldn't remember, my shrink said, "but you are remembering." That made me relax about not having full awareness and let the process go through me. It was actually a profound experience in the end. And changed my sense of how trauma is both experienced and worked through.
