I had things like that with my former T. Not around being scared or freezing, but he had a bunch of ideas he liked about how humans and the psyche works and he believed those to be universal truths (he told me so). Eventually, he tried to impose them on me as well, triggered by something that, for me, felt very insignificant (for me, but I did try to look at it from multiple angles). Then he ignored most other things and just wanted to dig that hole further, denying that he was pretty much digging it himself, based on his beliefs, further and further away from me. For us, it led to conflict upon conflict and eventually my leaving. Not suggesting your experience is similar, just this story of mine came to mind reading your post.

Another thing I wonder... this phenomenon of being unsafe and scared of people... you are a therapist as well, right? Do you experience anything like that with your clients?
