Silent Night, Eyes Shut Tight

"As Christmas drew near, my little sister claimed she’d seen Santa Claus in the house.“He had four legs, real long, like dead branches. He crawled on the floor like a dog. His mouth was full of teeth, and I saw him with my own eyes, climbing out of the chimney. His bones were making this clicking, clacking sound.”The Santa she described was nothing like the legends.My parents and I thought it was just her imagination.Until I posted about it online.A user named “NocturneNotes” insisted my sister wasn’t lying, and that the thing was dangerous.Panicked, I asked him what we should do.He gave me three rules:“On Christmas Eve, from 11:30 PM to 2:00 AM, the entire family must ‘sleep’ by the Christmas tree.”“You can’t actually fall asleep, or you’ll die in your sleep.”“No matter what you hear or feel, you absolutely cannot open your eyes or stop pretending to be asleep. Once it hits 2:00 AM, it will leave on its own.”"
