Universal scale wish

' Be careful what you wish for beacouse it might come true ' When you wish for something you don't exept it to work, but it does. When at middle school you wish to get an 6 at your Math test but you don't you easly forgot about your wish. But then at Collage you get 6 at your Math test even thought you didn't study why would you connect it to the wish you made way earlier? At most you think you are lucky and that's it. When a star falls it becomes a wishing star, if you think about your wish at the time its falling it will come true. It might take time or the star misunderstoods your wish. You wish for world destruction? Which world? You wish for your parents to come alive? As undeads or living creatures?
