(((shattered sanity)))

I really don't like those out of body experiences, everything feels and sounds very foreign to me. They seem to occur when I'm dealing with a lot of stuff at once. Does the T that you're seeing have decent experience with dissociation? If so, perhaps you can try bringing up specific descriptions of the experiences, to give him/her a better understanding of where you currently are emotionally.

I'd advise you to be honest about the fact that it scares the bejeezers out of you & you need help in developing techniques to making these events occur less often (with less intensity as well). If he/she doesn't have any words of wisdom on this concept, perhaps you should find another T with a greater understanding of the disorder.
