A Dream is A Wish Your Heart Makes...

I had that song running through my head today, and I thought, if a dream IS a wish your heart makes, then what on earth are my wishes? Because to be honest, most of my dreams are very strange, and I think that most, with a couple of exceptions, I would not want to come true. For example, a dream that I had in probably fifth grade. But in my dream I'm in third grade. I'm sitting in a classroom that is floating in outer space. I can practically see the rings of Saturn from where I'm sitting. At the front of the classroom is my teacher, and she tells me that I get an "A" for blowing up the earth. Now, what kind of wish is that? Because I have absolutely no desire to blow up the earth, I can tell you that. The thing is, I remember a lot of my dreams, as a matter of fact, I have a dream journal that I write them down in, but most of them I would not want to come true in any way, shape, or form. So, it just makes me think, what on earth were those people thinking when they came up with that song?
