1. Y-yeah, I think so, but I'm not really sure. I'm rarely ever conscious of myself in my dreams. When I am, it's usually to discover some awful fact, like being a guy.
2. Yeah, I think so. But I wasn't aware of myself either, so can't say whether I was a girl. Most of my sex dreams were bad though. Like one where I was locked into a room and forced to watch a one-night couple of perverted gays have sex, looking at me and spraying stuff on me. Ew.
