I also believe that dreams consist of content that "has gotten into your head", however strangely it may express itself when freed from the voluntary control processes. One thing I've found is that a dream can show you what's really in your "heart", before you've really sorted out a situation rationally.

I had been dating a young woman for a few months. She was under 4 ft tall, and wasn't "stacked", but I hadn't really thought about any clinical implications of that. She then told me that, by accident of birth, she had never fully developed sexually; she could make love, but never have children. I had no more than fallen asleep that night when I had just a few moments of dream; she came to me, nude, and I took her in my arms. It wasn't an "erotic" dream as such, but it was a happy one; I awoke immediately, and knew in that moment that I had no problem accepting her as she was.

The relationship ended for other reasons, but she is one of those I remember sometimes, and hope that life has been good for her.
