I have, though they haven't been really explicit.
I've never told T, much less described such a dream. The most I've managed is saying I've erotic transference and have had dreams around them. She asked what kind of dreams and I mumbled that I've dreamt of kissing her.
You're brave! I don't think I could even say aloud I've dreamed of her undressed. It's odd because I've been open with her about being much more attracted to women rather than men. *blush furiously*
