Sure. Fiction can be based on a true story. Think about historical fiction. Writers take a period in history that actually happened and create fictional characters within that setting. It's a way to bring history to life in a more engaging way. A lot of movies are like this too. They might be based on a true crime or a real - life adventure, but with some fictionalized elements for the sake of entertainment.
Yes, it can. Many works of fiction draw inspiration from real - life events or people. For example, 'The Great Gatsby' has elements that are based on the Jazz Age society that F. Scott Fitzgerald was a part of. Authors often take a true story and then use their creativity to add fictional elements like different character traits, altered plot lines, or fictional settings to make it a more engaging and unique fictional work.
Halloween is mostly fiction. It's a holiday filled with spooky elements and traditions that are created for entertainment and fun rather than being rooted in real events.
