Yeah, I do that too. Especially after the deep sessions. It is scary. One thing that can help some is to change the subject at the end and talk about something else for long enough to get grounded a bit. But if you sit in your car for half an hour writing down the things from the session that you need to try to remember, the dissociation comes back again.

The other thing that I do is I have books on tape, and I plan what I'm listening to so that I'll hopefully be involved in the story at the time when I'm driving home. I can tell when either the story isn't powerful enough, or the session was really intense, when I barely even notice when a CD finishes and I have to listen to it again because I didn't catch enough to know what's going on. But if I get it right (choose a story that I can get into, and be far enough into it to care about the story), then it helps. I drive 2 1/2 hours each way for therapy, so if I'm dissociating too much to drive that's a big problem.
