STORY: “Alright… this sounds fake, but it actually happened. So my friend was home alone one night. His parents were out, and it was like… around 1 AM. Everything was normal at first. He was just in his room, on his phone, lights off… just chilling. Then he heard a knock. Not at the front door… but on his window. The weird part is… his room is on the SECOND FLOOR. He thought it was just something hitting the glass… like a branch or something. So he ignored it. 15 likes for part 2!!!!!!!
