Have you ever experienced coincidence before? I am sure you did, somehow, somewhere, sometime. How about a coincidence that you 'experienced' in your mind? Hm, maybe that is just a wish. Well, I come out with this idea that coincidence is coincidence because you can't predict it, and if you happened to think about it, you have somehow disturbed the quantum state of the universe, and it just slips into another parallel-verse.
