It looked like nothing at first — just a faint, dusty line creeping up the wall above a clock. Harmless, maybe even forgettable. But within 18 days, it grew into a thick, winding trail of soil that didn’t belong… and what started as curiosity turned into full-blown panic when Reddit users sounded the alarm:
