You could also write a fanfic that focuses on a particular human character's encounter with the world of dreams in a more in - depth way. Maybe a character who has recurring nightmares and how they try to deal with it while being in this strange dream world, and how their actions might attract the attention of Dream or other entities in the Sandman universe.
One idea could be exploring the backstories of minor characters in The Sandman. For example, delving deeper into the life of a dream creature that we only see briefly in the original work.
Another interesting concept for a Sandman fanfic is to create an alternate universe where Dream and his siblings have different relationships or powers. This could lead to very different storylines and interactions.
One interesting Sandman fanfiction could be the one where the main character interacts with different dream realms in a new way. It might show the exploration of forgotten dreams and how they can impact the waking world.
Well, in '1984 fanfic', one interesting idea could be exploring different endings. Maybe the main character manages to overthrow the totalitarian regime in a way not shown in the original. Another could be delving deeper into the relationships between characters that were only hinted at in '1984'. For example, the relationship between Winston and Julia could be explored further, like what if they had a chance to start a real family in a post - Big Brother world.
Another concept could be the different dreamscapes. Instead of the typical dream settings, the fanfiction might introduce dream worlds inspired by various cultures or mythologies. This would make the exploration of the dream realm much more diverse and exciting, with new challenges and wonders for the characters to encounter.
A kyman fanfic could explore the idea of them getting lost in a mysterious forest during a camping trip. As they try to find their way out, they face various challenges that make them see each other in a new light. Or perhaps a story where they both enter a video game world and have to team up to defeat the final boss. In this world, their usual animosity is put aside as they focus on the game objective.
One idea could be to explore an alternate timeline where Ichigo never became a Soul Reaper. Maybe he lives a normal life, but strange spiritual events still occur around him, drawing him into the world of the Hollows and Soul Reapers in a different way. Another idea is to focus on a side character, like Uryu, and tell a story from his perspective during a major arc that we didn't see much of in the original series. For example, his experiences during the Arrancar arc when he was off on his own missions.
One idea could be a fanfic that focuses on Elsa's further exploration of her powers. Maybe she discovers a new aspect of her magic in a far - off land. Another could be a story about Anna and Kristoff's adventures during their honeymoon. They could encounter new magical creatures. And a third idea is a fanfic that delves into the backstory of the Northuldra people, showing more of their culture and history before the events of Frozen 2.
You could create a fanfic where the characters go on a road trip across the country. They'd encounter different cultures and situations, which would be a great way to show their growth and how they interact with the outside world. It could also be funny to see how they deal with things outside of their familiar neighborhood.
A really cool idea for a 'the incredibles fanfic' would be to have the Incredibles travel to a different dimension. In this new dimension, the rules of superpowers are different, and they have to adapt quickly. They could meet alternate versions of themselves or new allies and enemies. This would open up a whole new world of possibilities for the story.
One idea could be to explore the backstories of the minor characters in more detail. For example, the character who only appears briefly in the original but has a really interesting look or a single line that makes you wonder about their past.
One idea could be a time - travel fanfic where Naruto or Sasuke go back in time and try to change certain events. This would allow for a lot of creative storytelling as they interact with their younger selves and try to prevent future tragedies.
