I always thought regret was just a lesson—something you could sidestep if you listened hard enough. So, at 21, I started collecting stories. I’d ask people late at night, in dim corners of cafes, on empty buses: What’s your biggest regret? Most answers blurred together. Until her. She sat across from me, eyes too wide, voice a rasp. “My regret?” she said. “Letting him in.” She never said who. But after that night, my phone started buzzing at 3:17 AM. No number. Just static. Sometimes, a voice—my own—whispering, “Let me in.” I don’t ask strangers about regret anymore. But every night, I hear knocking. And I know exactly what I regret. #TrueHorror #UrbanLegends #SleepWithTheLightsOn #Spirituality
