I don't know if your T is aware that you are recording. I record because I have DID and bad dissociation so my T actually suggested it so I could review what I missed in session.

I have played back certain things he has said before and he was happy to explain what he meant at the time. Is this an option for you?

Maybe you do have hallucination or paranoia issues and your T is not aware if it. You can take meds to help with that.
