It's been a long time since I had a sex dream. I think my libido is slowly dying as there has been little movement down there.

When you dream, your body releases a natural chemical known as DMT, so when you dream, it's like an unconsious (sp?) trip. You dream because this chemical is making you dream.

Joe Rogan had a little say on that on a radio show awhile back. It's kind of interesting actually.
