I just finished reading a scholarly article re: how thoughts of a client can be transferred to the therapist, so that they both have the same thought. It was a paper on projective identification, which is a rather primitive defense mechanism in psychoanalytic and psychotherapeutic processes. Apparently, Ts tend not to admit to how this phenomena takes place, but most are extremely interested in the subject. Perhaps, your T had some thought about this, thus his silence. You might ask him?
