Yes I have become somewhat aware of dissociative attacks as you call them, I experience them upon waking from dreams and nightmares, when I wake up, I am already switched, everything is fuzzy, feels strange and I will experience pain or feel things that are not "me" so to speak, like pain, touching, etc.
When I am talking in therapy, even though I am not scared of T in my head, my body is. My T said is it like my body is still in trauma mode, physically I am very withdrawn posturely, on alert, tense ready to flee but mentally I am very connected with her, and not overwhelmed. My head and body are disconnected, even though I believe I am safe and okay, my body experience is a very different thing, I feel like I have run a marathon after each session, or like I have beaten up and physically hurt, standing after a session is painful. A lot of my abuse was very physical, so maybe that is why I have so many of the somatoform issues, but they fortunately aren't triggered as much any more, except at night.
I now am focusing more on somatic therapy, which has really helped me be more aware of physically what is happening, my body numbing has decreased, as has my reflux, and on going back issues, which I have had for years.
I now know the EP was out front in a session with an older T, when I lost my full eye sight until he was able to help me ground myself, it was really frightening when he was there and then I made him disappear, and I couldn't see, but I don't always experience it like that. Mostly my T is brings my attention to it, because she sees it, but for me it has always been there so I am not as self aware, unless it is a very painful episode. It's not always possible to distinguish real pain from the other, the only way I know it is different is that I can make it disappear
