I do believe dreams can predict the future and help solve problems. I think there was a quote from the X-Files once that went like "Dreams are the answer to question we haven't learned how to ask." Subconscious cogitation, desires, fears, all can come out in your dreams. One of the most interesting experiences I had is when I had coder's block on a program I was writing for school and in the middle of the night, an old man came to me and told me how to fix the program. I don't necessarily believe there's anything paranormal about that or dreams in general. I think their problem solving and sometimes prognostic qualities come from your mind just crunching the numbers behind the scenes. I tend to always go back to Occam's Razor in these sort of topics, though going back to the X-Files agian, Mulder called it: Occam's principle of limited imagination, haha. Sorry, I'm a sci-fi nut. My love for sci-fi is probably a knee-jerk response to the fact that I believe in an ordered and explainable universe.
