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

Jeff had always been fascinated by the strange folk tales his grandmother would tell him late at night when he was a kid. One in particular was of a portal that could take him to other dimensions. One night, after hearing the story again, Jeff decided to try and find the portal. After many hours of searching, he finally located it in his grandmother’s attic. Upon entering, he was transported to a different world. Here, he met a strange creature called a naga. The naga offered to take him to another dimension, but Jeff refused. Suddenly, Jeff lost consciousness and when he woke up, he was back in his grandmother’s attic. He never told anyone about his encounter with the naga.
