It used to be a mix for me... sometimes male, sometimes female, sometimes a hybrid. The awful thing was whenever I WAS male, I knew it was wrong, and tried to become female (most of my dreams are lucid). I couldn't escape the GID, not even when I slept.
When I was female however, much of the time it was accompanied with the thought, "Wow! Cool! I did it!" I was more or less aware that I USED to be male, or was so in Real Life.
For a year or so now though, I've been exclusively female in my dreams, without any self-consciousness whatsoever. It's just normal, ordinary me, Kate, doing her thing. I'm guessing it's because I stopped thinking of myself as being male altogether, whereas before I kinda imagined GID as being a condition where I, as a male, wanted or needed to be a female. I felt guilty for it, and had difficulty accepting the fact that I AM female, regardless of my anatomy.
Once I finally accepted myself, and stopped making excuses and justifications, everything fell into place and became a coherent whole, both in my waking world AND in my dreams 😉
