I jerked awake, scared out of my wits, and leaped out of bed. The sound was coming from somewhere on the first floor.
There it was again! An echoey, hollow-sounding bang. Baseball bat in hand, my heart going like a trip-hammer, I tiptoed through the house. Once in the kitchen, I realized it was being caused by something smashing, over and over, against the inside of the closed refrigerator door.
I stood staring at the door in pants-pissing terror, wondering what exactly that horrible banging, and now low, eerie snarling could be, because there was nothing in there but eggs.
Author’s note: One day, I heard a really strange sound come from my always quiet refrigerator.
