i can see when they start switching into parts whn they're dissociatend. I'm watching people's eyes, their eyes give wide and go off to the side. And you can clearly see they're starting to inter acter the reality that's not the one that's here. An when you trigger apart, talking about a dramatic discussion, you can see a change in people's body language. When they don't want to talk other any more, they thy'll swish. The only way to help some one re regulate is to help them ground back to the present.
