22. One time when I was about 8, back when kids were allowed to run free range in our country neighborhood. I came back early from playing with some neighbors and went to sleep on the couch as I was tired from running rampant. My parents thought I was still at the neighbors house so they left to go to the store.
When I woke up, it was dark and the power had gone out. I climbed off the couch and started calling for my mom when I started hearing noises from the basement which I never went down to anyways because it scared the shit out of me at that age.
It was a scratching noise, like something with claws was dragging against the concrete floor.
Naturally I was scared shitless so I ran back to the couch, climbed into the hole underneath the cushions and waited until my parents got home. It only took them 20 minutes but to an 8 year old scared of being eaten by some basement monster, it felt like hours.
