Oh yes! I've talked about my dreams in T, and with my T being gestalt-based, it generally leads to a lot of self-discovery. In gestalt therapy, it is believed that each part of the dream symbolizes parts of ourselves. We approach it in different ways in therapy, but the one that comes to mind at the moment is picking a particular object of the dream and giving it a voice....and seeing where that leads. It's definitely worth bringing up!
