I would be interested to ask my T about this but I'm not sure she'd entertain the conversation...Mostly because I don't think she is one who often remembers her dreams.
I have only had two dreams about my T and one of them was last night! There was a scheduling mishap and people in the office and my T were telling me I had missed my appointment, but I had a card to prove I came at the right time. She was super mean about the situation and I left feeling so bad. I don't know why, since she is never mean in reality.
In another dream we were in a "black abyss" (no room, just darkness around us) but we were illuminated. We were sitting in chairs across from one another and I was crying and asked her something. She sat there blankly and stared at me the entire time. Apparently when someone is silent in a dream it represents one's skepticism about the person and wavering trust in them. You are still trying to "figure them out". I found that interesting.
