I started hearing something under the floor of my room at night. At first, I ignored it. Old house… pipes… settling wood… there’s always an explanation if you want one. But it kept happening. Every night. Right under my bed. --- It wasn’t loud. Just slow movement. Careful. Like something was there… but didn’t want to be noticed. --- Most nights, it stayed the same. A few seconds of movement… then silence. But one night was different. --- I woke up suddenly. No reason. No noise
