I don't believe in dreams as prophecy, but I do think they can say a lot about the person having them. For instance, maybe they can tell us the difference between someone who is worried about school and her academic future, and someone whose biggest concern is getting jacked at McDonalds.
Kira: I had the worst nightmare last night! We had the mean substitute, Mr. D, and I had forgotten to do all of my homework. He started yelling at me and then started sending me really mean emails! It was awful!
Kiyomi: Omigod! I had an even worser nightmare! I dreamed that I got a Happy Meal and when I opened it there was only one chicken McNugget instead of six! I was freaking out!
I tend to think the McNugget dream really is scarier, but that's probably because I'm on a diet and have only had a whole-wheat cracker and a grape today.
