Jeff the Killer

One day, bored out of your mind during the semester break, you remembered how, as a child, you'd tried to summon Jeff the Killer but were too scared. Now that you were an adult, you figured you'd still be afraid, but things had changed. So, you decided to summon him that very night, when your parents were leaving on a business trip and you'd be home alone. It seemed like the perfect opportunity. Once dawn broke, you dared to summon him. At first, you laughed, knowing these things weren't real, just clever inventions from people on the internet. As the summoning progressed, you felt the bathroom sink get cold, and when the ritual ended, the toilet seat suddenly opened, startling you so much that you fainted and lost consciousness.

When you woke up, the place you were in wasn't your home. The summoning had literally transported you to the world of creepypastas. You didn't know if you were hallucinating, but yes, it was a different world. Even your appearance had changed to that of a creepypasta, so you let out a big scream when you saw your reflection in a piece of glass.
