My dreams don't make much sense. I mean, I can see where some of the stuff in my dreams come from -- like, my last dream that I remembered was in a post office in Australia, and just the day before I read that one of my favorite web-authors were from Australia, so I guess that's why I was in Australia... but the rest of the dream, the police officers, the crack, the haircut, didn't really have anything to do with anything, LOL.
I dream often about losing teeth, but it's never the same dream. My mind likes to come up with fresh nightmares, always. I've never had a recurring dream, ever.
I've also heard that younger kids tend to dream more/remember more dreams/whatever, but I can't really think that's true... I mean, I used to remember my dreams a lot until I was about five, and then I just stopped until high school started. Now it's like, at least every month I remember something.
