Hello lifeamateur: Honestly, I would have no idea why your therapist would blurt something like this out.

Perhaps he was simply offering up a rationale for why you are receiving the harassment you are getting?

Personally I would doubt that there was some clandestine testing going on. But I suppose anything is possible.

I do think that, since this is clearly of concern to you, it is important to discuss it with him. Assuming that he is a skilled therapist, he should not be "put off" by the fact that you raise the concern.
