About 99% of my dreams are very vivid and extremely random. Most of them don't make sense at all. In most of my dreams, I begin as one animal and change to like three different animals during the course of the dream. I can think of a few times, though, when my subconscious was...trying to tell me something. I remember when I was in middle school and I dreamt that I had a girlfriend (who also happened to be Raven from the good original Teen Titans) and we were cuddling together.
Then I had another one a few months later where I was in "mindspace" (idk my dream-mind comes up with really weird alternate universes every night, and that night I was in something vaguely similar to nightmare realm and The Matrix) and there was an evil giant Cheshire cat that "wanted to play" (meaning causing infinite torment for me and everyone else in mindspace, who were all also me) and it was locked in this pitch-black room that was illuminated by only a barely perceptible glow coming from me) in a lab. And I rescued a really cute girl from inside, and I did the old "dip-kiss" thing that I would never be able to do in real life because I'm not strong enough. So that was shortly before I realized that I was queer in one sense...I've had several "epiphanies" since then. <|:P
Also there was this one dream where I had a perfectly flat chest and I was walking down the halls and people were using male pronouns! And it was before I had come out to anyone. It was cool, until I woke up.
Anyway, what I'm trying to get at is, yes. But rarely.
