Yeah, think about if you were actually colorblind and didn't know?
Or this!
You're actually in the future, and you're on a reality TV show all about you and how you react to life. All events that have happened to you have been planned by some producer, and your world is inside a giant dome that simulates temperature, weather, time, and everything else. Everyone you know is an actor on this TV show. Your parents aren't actually your parents, and you were grown in a test tube from artificial DNA. The money system, government, planet, and world that you know is completely fictional, made up by a creative group of TV producers.
