Murder in the dark
My childhood home had 13 steps leading into the basement. I remember the number exactly because I always counted them as a child when I sprinted up trying to outrun the monster I imagined lived in the furnace room at the foot of the stairs - the monster that chased me, right on my heels, all the way up the stairs. My brothers and I used to play a game in the basement called “murder in the dark.” We turned off the lights so it was pitch black. Then we roamed around in the darkness with outstretched arms, screaming, trying to tag one another. Probably annoyed the hell out of Mom.
