I got a call from a No Caller ID at 3AM. I ignored it. It called again. And again. On the fourth time, I answered. No one spoke. Just breathing. Slow. Heavy breathing. Then the voice said, “Look outside.” My heart started racing. I live on the second floor. There was no reason for anyone to be outside my window. But I walked over anyway. And that’s when my phone buzzed again. Another message. It said, “Too late.”
