Strange...I thought I had posted a reply, but I'm not seeing it. I hope I don't end up double posting.
Most of the dreams that I remember, I'm not really any specific gender, or that's not the aspect of the dream that stays with me, but I have been having a recurring dream where I'm post-transition, and with old friends I played music with, who knew me as male. In the dream, we're trying to put old bands back together or start new musical projects, and while my presentation as female isn't an issue to anyone at all, everyone in the dream does have a real problem with the tone of my bass and the style of my playing, both of which are really the same as they ever were in the past, in real life. They keep asking me to turn/tone it down, because it doesn't really fit with the music anymore.
There's probably some fairly rich stuff to mine there with my therapist, but I haven't brought it up to her yet.
