Thanks for sharing your experience. Will you try it again?
I had a handful of hypnosis sessions with a former T and my experience seems similar to yours. The relaxation part was kind of nice, but responding to the questions was very concrete and analytical. There were no insights & no new material was uncovered. The T was surprised it didn't work.
When I later tried analysis, I was interested to find that it provided a much more productive state of reverie, a refreshing detour around my conscious experience and an endless source of new material.
I am curious to try hypnosis again with another T, though, to see if I get different results.
