Ahh, I strongly believe that dreams are a sign, a prophecy... I often have dreams that seem to foretell the future; at times they're scarily detailed and realistic. Heck, sometimes I have dreams while I'm awake! (LOL) I believe that dreams are messages from spirits.. and the ones that foretell your future are just possible outcomes of the future. It may be extremely easy (at times) to change that outcome you saw while at other times they may be inevitable.
