It's kinda funny, but in reading this thread I've realized that on several occasions I have asked my T if I could see my entire file, including session notes. Each time she has said that I could if I really wanted to, but each time I have backed down and not followed through. I think I need to feel like I have a choice, that I know I can if I want to. But I have never followed through, either because I get scared that it will not be good for me or because I end up relaxing enough to not hold onto that motive of distrust.
I have asked my T before, as she is scribbling, Did she just write such and such down that I had said? And she will tell me yes or no. So sometimes I do know --without actually reading-- parts of what she writes. I don't think my T is very technical in what she writes because the times when she has read back to me what she has written it is always plain English to me. Mostly it is just summarizing what we have talked about that session, and she will often include a few direct quotes from me which she thinks are significant. I've asked T before how she decides which of my statements are important enough to write down and which ones she can leave out, and she smiled and said, "I just know." That was kind of a frustrating answer.
