That happens quite a bit in my therapy. My therapist assumes I am being shut down/have switched/am experiencing a trauma response and tries several different strategies to reorient my and my alters to the present. Strategies such as...
- asking us to count objects in the room/feel the chair under our body/notice the sound of the music playing outside/touch the soft toy that we take
- her repeating statements about the present (it's 2019/the danger is over/it's safe now/we're sitting in this room together/no-one else is here
- throwing a ball to each other/each of us pulling on the ends of blanket/rolling a ball across the floor to each other

Most often one or a combination of those strategies help us climb out of it within a minute or three.

I need to say I TOLD my T to use these things when I get shut down, she did try some other strategies but I found these ones most helpful. When something helps I tell my T at a more neutral (untriggered) time so she knows to use them again. Working together like this has helped us feel a lot safer in therapy.

What does your T do, Fuzzy?
