I've tried to do this before when I was doing CBT and they were saying things like 'how would someone feel in this situation' but I just ended up coming up with 'it depends what kind of person they are' - haha.

One therapist once did a great thing with me where to try and investigate how I felt about things I picked up stones and objects and so on that she brought to the room. And I would pick up a stone that remind me of Mam, pick up a stone that reminded me of Dad, and one that reminded me of my brother, and then talk about the similarities between the stone and those people, which helped me to focus on what it was I felt about them and helped me use 'physical' words, like 'spiky', for instance, and then I would be able to metaphorically connect the idea of 'spiky' to what kind of characteristics that person had and what 'spiky' feels like in emotional terms.
