Try being a transsexual and having those dreams. Imagine being back there, made to wear dresses, having long hair, and trying desperately in the dream to find a pair of clippers or a razor or something so you could shave your head. Stuck back at CEDU as a girl, forced to be a girl, even though I am a man now.
I don't have those girl dreams as much as before, but when I do, they are always frustrating and disturbing. "Oh god, I'm back where I started. I'm going to have to go through my transition all over again."
