I found that when my T (and now, others) see something in me, that's what they see and it is a good idea to stop and look and try to see things from their eyes. They have no reason to make stuff up (and if they didn't see it they'd have to make stuff up from thin air). If you are getting angry at her because she is saying these things (instead of being puzzled or not caring because it does not fit) and throwing pillows at her, I'd look again to try and see what she is seeing. No one else can make you angry, how we feel always comes from inside, not outside.

Next time she brings it up, act surprised and say, "Really? What do you see?" and see what happens.
