At exactly 2:17 AM, I woke up to a sound.
*Knock. Knock. Knock.*
It was faint… but clear.
I checked my door. Nothing. My window. Locked.
Then it came again.
*Knock. Knock. Knock.*
This time, I realized where it was coming from.
My wall.
Right behind my bed.
I live alone. There’s nothing on the other side of that wall—just empty space.
I told myself it was pipes. Old buildings make noise. That’s normal.
But then it happened again.
Closer.
Slower.
