I know my therapist thinks of me when he reads certain articles or sees things on TV that remind him of me, because he tells me so.

But I also think he thinks about our sessions in ways he does not discuss with me, sometimes potentially a lot when there is intense stuff going on. I don't think he's obsessed with me or anything inappropriate. I just think when there's a period of very hard work going on in therapy, therapists get emotionally entangled and it is inevitably going to stir up thoughts and feelings in them.
