Interesting, MKAC. It seems to be related to the hypervigilance that comes from trauma. My T told me that those who most often or deeply experience dissociation are also most likely to be hypervigilant, always scanning their environment for cues of danger, and acting on their perceptions, but largely unaware of it. It becomes second nature.

I wonder if part of his discomfort could have been because he could feel your perception, but wasn't conscious of it?

That was one of the things my T noticed about me in that counter transferential way--an intensity.
