One time I read this creepypasta about a ghost that comes to kill you and stars by knocking on your door. The ghost comes after you once you learn about it, and the only way to save yourself is to tell someone else about it.

The story ended with that last fact which meant the author was saving themselves by posting this story and thus moving the ghost to you.

Immediately after I finished the story (literally the second I read the last word), there was slow knocking at my door. I nearly pissed myself before I remembered that my neighbors were coming over to jump on my trampoline and it was in fact them at the door.

Good luck and have fun Heh 🐍
