I use to get something a little similar; when I'd be "reminded" of something, kind of triggered I guess, and a thought/idea I'd been suppressing would come to mind and hit me full force and there'd be a "lightning" chain of thoughts go through my head; I felt like a covey of quail had all taken flight from hiding at once :-)

My face would do really crazy things, get really mobile; all the feelings I was experiencing going across it at once. My T once laughed, it looks so strange (and I could feel that it looked strange so didn't mind her laughing and she apologize, it was a reflex on her part to laugh just like the face I made I couldn't help either). After it would "let me go" it would be suddenly really quiet in my head and I'd gingerly "look around" to see what had happened. Usually things had done a major shift because of the "new" information I had because the suppressed thought was now unsuppressed.

I started thinking of it as my brain getting tired of doing things/growing the slow way, had gotten frustrated waiting for me to understand, get insights, etc. in therapy and instead "Someone" had just grabbed the wiring and realigned all the synapses all at once for me :-)

Can you remember what you are thinking about after the episode? Are there any changes in you?

The better I got in therapy the less often it happened. But when I have things like that I am so interested in them that I ignore if other people see or what they think and try to figure them out for me so I understand them. I laugh at it too because I know it must look funny because it really feels peculiar!
