Hello again and thanks for your answers and support.
I talked to him on the phone. He answered calmly and was not surprised at all, like he was expecting such a conversation. But he did not confirm that anything unusual has happened during the sessions. He insisted that he uses a unique method of hypnotherapy which is not used regularly. All in all he said it's totally fine, don't come. But let me know when you want to come back! Like he was sure I am going to go back to him again.
He was weird and said I knew you will make this phone call. Sometimes I feel like he can read my mind!
I am still confused. I don't know if it was the right thing to do.
