Call… I was home alone… just scrolling on my phone. Then I got a call from a random number. I almost ignored it… but something told me to answer. I said, “Hello?” And I heard… my own voice. It said: “Don’t look behind you.” I froze. I laughed a little, like it had to be a prank. So I turned around anyway. Nothing. I went back to my phone. Then the voice said: “I said don’t look… because now it knows you can see it.” My heart dropped. I whispered, “See what…?” The call went silent.
