The quotation wasn't intended to be fully descriptive of anyone's experience, including mine.
That said, it resonates strongly with me.
I don't agree with your analysis. If, as is commonly, perhaps simplistically, believed, our personalities, our essential beings, are the result of experience combined with biology or genetics or some natural and inevitable factor that is not easily summed up in one word,
then I am, in part, the product of my trauma. Even a statement like "I'm not going to let this define me" is a product of whatever the 'this' is.
In my own experience, which is difficult for me to discuss, which might be considered a product of the experience itself, there are a number of topics where my feelings, my acceptance or rejection, my revulsion even, come with the question of 'where did that come from?' which sometimes turns into the question 'Who gave me this?'
To borrow your example. I'm thinking of a leather sleepsack. This is not something that I have any personal or even secondhand experience with. The sensation of my skin crawling, the sudden catch in my throat, the feeling of hot nausea, is all coming from somewhere. Where is it coming from? My intense revulsion at having my face covered, of feeling warm breath, my own or someone else's coming back into my face (the whole Covid mask thing is a real funfest for me) comes with vague, disjointed memories of something awful happening, something I could not escape.
The dissociative episodes that have occurred related to certain situations did not happen because I embraced a negative thought. Positive thinking and reframing has a place in coping, I believe. With enough gentle, loving exposure and practice, and enough positive reinforcement, and enough reframing of my own reactions and thoughts, I think, perhaps foolishly given my past experiences, that I could feel some positive, arousing, loving things while someone I trust and love deeply laces or zips up or otherwise secures a full body covering thing around me.
But that addresses a single reaction and not the root cause of my whatever. My issues? My past? My questions of "Who gave me this?"
Again, maybe not the most cogent thing I've ever written. More like a stream of spew from a container labeled "Contents Under Pressure" The best I can manage right now.
Sincerely,
Eido
