Author commentary: The kids all write stuff on their walls that's invisible to them. Or their subconscious is blocking them from seeing it or something. They are troubled by the visions of their unwoken dream selves, who force them to sleepwalk and scrawl things on their walls. What must their guardians think? Oh right, John's dad saw a bunch of gross clown graffiti on John's walls and assumed it meant John loved clowns, thus spurring Dad to get really into clowns himself to support his son's interest. What a dad. When Rose's mom saw her daughter's graffiti, she probably just thought something like, "I am currently too inebriated to show any concern about this. Anyway, time to continue getting hammered and admire my wizards some more."
