Okay, I've been thinking and have some theories. Once, when i was talking to my T about something, or rather he was talking to me, he reminded me of my someone from my past who frightened me as a child. I freaked out but wasn't able to tell him about it for a couple of weeks. I think this was negative transference, maybe. As I was just reading ErinBear's post about her former T, that situation sounds like negative transference from T to patient/client.
Anyway, just a thought, or a couple of thoughts......
