The gap between fact and fantasy is not always as clear as we might expect. We can get so excited about the way we wish things were that we twist and distort reality to try to make it match that vision. Or we may cling to a dream so resolutely and intently that we almost force it to come true, against all odds. Sometimes, the inability to distinguish clearly is a disadvantage. And sometimes, it's the most helpful gift the cosmos could ever give us.
