Apt - I feel that way too about not dealing with other people. It waxes and wanes for me, but is always present at some level.

LC - for me it can be a floaty drugged feeling. The one therapist asks where I have gone and labels me resistant if she notices, and the other asks me to describe the feeling and tells me it is a sign I am being overwhelmed and so then she takes things back a step or two to help me.
I can get it other places too.
