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

Tommy was just about to bedtime when he heard a strange noise coming from his parent’s room. Curiosity getting the better of him, he slowly opened the door. What he saw shocked him to his core. Sitting on his parent’s bed was an old woman with shaggy, black hair. She was wearing a long, green dress and her eyes were bright green. Tommy felt a cold wind blowing through the room and before he could process what was happening, he found himself on the other side of the portal.
