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

Harry was bored. He had been working at the same job for the past five years, and nothing ever changed. He was always the same age, always living in the same city, and he was starting to get a little bit grouchy. So, one day, he decided to take a break and explore the city. After walking for hours, he found himself in an unfamiliar part of town. To his surprise, he found a portal opening up in the ground, and inside he saw a bright green world. He stepped through and found himself in a beautiful forest. There were talking animals, magical creatures, and a paradise-like landscape. Harry was so excited to find this place, and he decided to stay forever. However, when he returned to his world, he found that it had started to rain and snow, and everything looked a little bit different. He realized that this must have been a dream, and he returned to the portal and went back to his normal life.
