Prompt: Write a short story about a man who discovers a magical portal

John had always been fascinated by the supernatural. He loved watching movies and TV shows with scenes of witches casting spells and zombies rising from the grave. So when he stumbled upon a large, mysterious portal in his backyard one day, John was elated.

He hurried over to it, eager to explore its secrets. But as he got closer, he realized that the portal was not solid like the ground surrounding it. If he stepped through it, he would end up in some strange, otherworldly place.

John hesitated for a moment, then decided to test the portal’s limits. He stepped through it and disappeared into the dark beyond. What would happen next? John had no idea. But one thing was for sure: he was about to discover the world of the supernatural for himself.
