I used to think there were monsters in my bedroom. My wall was painted two colors at the time; white a little less than halfway up and pink below. As a way to reassure me that there were no monsters, my parents told me that the person at Lowes mixed in a special "Monster-Proof Fourmula" into the pink paint, and as long as I stayed below the white paint, I'd be safe.
I think this may have also been a way to stop me from getting up at night.
They still keep this up with my little sisters.
