One plot idea could be a haunted house. A family moves into an old, dilapidated mansion. Strange noises start at night, like creaking floorboards and whispering voices. Objects move on their own, and the family members start having nightmares about a dark figure that lurks in the shadows of the house. As they try to uncover the history of the place, they find out that a murder took place there decades ago and the spirit of the killer is still trapped.
One idea could be that the character who seems to be the hero is actually the villain all along. For example, in a story about a detective solving a crime, it turns out that the detective was the one who set up the crime in the first place to gain fame.
One idea could be that the seemingly innocent child character is actually the one causing all the horror. They have some sort of dark power that they are using to torment the adults around them. For example, they make people see their worst nightmares come to life.
Imagine a scientist who goes to an isolated research station in the Arctic. The station has a dark past that he's unaware of. As he conducts his experiments, strange things start to occur. Equipment malfunctions on its own, and he finds odd footprints in the snow outside that don't belong to any known animal. He begins to feel like he's being watched. Eventually, he uncovers a secret experiment that went wrong decades ago, and the mutated creatures from that experiment are now after him in the isolation of the Arctic.
One idea could be a time - travel plot. A character discovers a device or a magical portal that allows them to travel to different eras. They might have to fix historical mistakes or find a way to get back to their own time while facing challenges in the past or future, like dealing with different cultures, languages, and technologies. It can also involve a love story across time.
For a fantasy story, you could have a plot where a portal to different dimensions suddenly opens in a small town. Strange and wonderful creatures start coming through, but also some very dangerous ones. A group of locals has to figure out how to close the portal before their town is destroyed. Or there could be a story about a magical library that contains books that come to life. The librarian, who has no idea of the library's true nature at first, must protect the books from thieves who want to use their power for evil. A third plot might involve a fairy who loses her wings and has to go on a journey through the human world to find a way to get them back, all while learning about human emotions and values.
One plot idea could be a haunted house. A family moves into an old, dilapidated mansion. Strange noises start at night, like creaking floorboards and whispering voices. Objects move on their own, and shadowy figures are seen out of the corner of their eyes. The family tries to find out the history of the house and discovers a dark past of murders and occult practices.
A woman moves into a new apartment. Strange things start to happen like objects moving on their own. She believes it's a ghost. But it turns out that her ex - boyfriend has installed hidden cameras and is remotely moving things to make her think she's haunted. He's obsessed with her and wants to drive her crazy. This adds a more human - made horror element rather than the supernatural at first glance.
One plot idea could be a lost little puppy who goes on an adventure through the city to find its way home. Along the way, it meets different friendly animals like a wise old cat and a helpful squirrel that give it advice and help it avoid dangers.
A time - travel plot where a character accidentally travels back to a significant moment in history and has to figure out how to return while not changing the course of events too much.
