I would definitely share the dreams with T. I had not a nightmare, but a disconcerting dream with my T in it, and talking about it led to some good progress.
In the meantime, so maybe your subconscious doesn't have to keep plaguing you with these dreams night after night, try to write them down. Put as much detail as you can remember, and include any feelings you had while in the dream.
I'm sorry this is not fun..and I'm hoping you can get a good night's sleep very, very soon.
