Price of a Dream?

So I was thinking... Is there a price for a good dream? The reason I question this is recently I had the most amazing dream I have ever had, yet the day that followed was one of the worst ever! So is it possible that the price of that wonderful dream was a horrible day? Or am I... I donno... paranoid? Maybe I'm just crazy and it's all in my head. And then there's always the question of the opposite... Is the price for a good day, a bad dream? Oh and another thing about dreams... Does anyone believe that if you speak your dream, like speaking of your wish, that it will never happen?

Sorry that was really random, but it's been on my mind for a while.
