In her experience, some people who drift off are angry, and they don't want to acknowledge that anger, so she asked you about that.

She also asked where you were when you drifted off, as a way of understanding what you were feeling and thinking, what it was that made staying present and communicating seem like not a good idea.

She asked what you want from her also as a way of understanding where your thoughts were when you were drifted off. She wanted to know if you had any ideas about it and about what she could do for you when that happens. (I asked my therapist to ask my point blank why I felt like I needed to stop communicating - my choice of words and my request to her about what she could do.)

Something was there and she was interested in what that was.

All that you posted would be really good to go in and talk about with her next session. "_
