Ever since I was a little kid, I've had dreams where I'll wake up as a girl and I'll run to the mirror, and I'll start crying because I actually felt happy with my body. Those dreams would always hit the hardest because I'd soon wake up after that and find out it was just a dream.
While transitioning, I felt like I was becoming more "me", my true self, it's hard to describe. It's like a weight was gradually being lifted off of me.
The frequency of appearing as a woman increased post transition, but those dreams were already common pre transition too.
I hate being a man in my dreams, because that's not me, it doesn't feel like me, it'd be like waking up as a whole different person.
