Well, you could consider writing about personal growth and self-discovery. Have a character overcome obstacles and learn important lessons about themselves and life. Another option is mystery and crime-solving, where the reader follows along as the characters try to solve a puzzling case.
You could write about a magical adventure in a fantasy world. It's always popular and allows for a lot of creativity.
Adventure is another wonderful theme. You can take your characters on a journey to unknown lands. They might encounter strange creatures, face difficult terrains, and have to use their wits to survive. For example, a group of friends going on an expedition to a lost jungle.
Well, themes like curses or ancient evils can be very effective. The idea that something evil has been lurking for a long time and is now unleashed can be terrifying. Another option is body horror, where the physical transformation or deterioration of a character causes horror. For example, mutations or diseases that distort the body.
A story based on a real-life event or a historical period can be interesting too. It allows you to explore and bring to life a moment in time that people might not be familiar with.
How about a cursed object? Something that brings bad luck and horror to whoever possesses it. You can make up all kinds of creepy backstories and effects for it.
You could focus on haunted houses or creepy old cemeteries. They always give that spooky vibe.
How about a story set in a post-apocalyptic world? Imagine survivors struggling to rebuild and dealing with all the dangers and mysteries that come with it.
You could write about a missing valuable artifact and the detective's quest to find it. Or a mysterious disappearance of a person in a small town where everyone seems to have something to hide.
A good fiction story could be about a person's journey of self-discovery in a fantastical world. It allows for exploration of inner growth and new experiences.
How about a story based on a first love experience? It can explore all the emotions and challenges. Or a tale of a person trying to achieve a seemingly impossible dream. There are many possibilities to make it engaging.
