My t has been known to get up and close the blinds so I'll stop looking outside. He'll just get up and walk around, or change where he is sitting. He doesn't let me drift off. He generally tells me to tell him where I'm at, what am I thinking about, and he won't take "I don't know" as an answer. It's not that it is bad, it is just that I tend to dissociate, which really isn't helpful, so he works to keep me focused.
