T doesn't ask me 'where' but 'what'.

"What do you feel in your body right now?"

The first time he asked this I was like.. HUH! But then I realized my whole body was tingling or a feeling of lifting. I now can recognize this feeling when I am really dissociating.
Another time was extreme heat all through my body, and it was connected to shame. I get that feeling a lot when talking about childhood.

It gave me a bit of awareness, that I found somewhat helpful. I think if he asked me 'where' in my body I feel sadness or something, I would look at him like he had 2 heads.

I read a good book called: The Body Remembers. It's how traumatic memory is stored in the body. Might be a good read if you are going to be doing more of this work.
