One night, I was sitting in my room with my cousin. My room is on the fourth floor, so it’s practically impossible for anyone to be at the balcony door. Out of nowhere, we started hearing knocks — three sharp, deliberate taps ..

Knock. Knock. Knock. 🚪

We froze. At first, we thought maybe it was our imagination, but the sound came again. We checked outside immediately, but the balcony was completely empty. No wind. No loose objects. Nothing.

Yet, the knocks continued — always three, always perfectly spaced. It only happened that one night, about four months ago, but even now, whenever we meet, we always talk about it
