I don't have much help to offer. I'm not dissociative, I'm always here. It's what I am that changes for me.

With Asperger's one can be sort of overly sensitive, not only to impressions and the world, but toward the inner world as well. However, JUST Asperger's does not explain what you are describing. It might be that your sensitivity opened some doors to something else. IMO it would need to be looked into separately, if you have a good doctor you could try to run it by them.
