You could write a story about a little girl's ghost. She died in a tragic accident in a school. Now, at night, her figure can be seen in the empty classrooms, writing on the chalkboards with invisible chalk. Her sad sobs echo through the hallways, and she often appears to students who stay late to study, scaring them half to death.
A ghost story about a vengeful spirit in an old family mansion. The family was involved in some dark secrets in the past, like murdering a servant. Now, the servant's ghost makes strange noises at night, moves objects, and leaves cold spots throughout the house. It especially targets the descendants of the family who wronged it.
Another idea is a cursed object. For example, a beautiful antique mirror. Whoever looks into it starts to see a distorted version of themselves that slowly becomes more and more menacing. Then, bad things start to happen to them in real life - they get into accidents, lose their jobs, or their loved ones start to act strangely towards them as if they are being influenced by the mirror's curse.
One cool idea could be a haunted house where the walls ooze blood and the rooms shift randomly. Every time someone tries to escape, they find themselves back in the scariest room.
A young woman moves into an old apartment. Every night, she hears a baby crying from the empty room next door. When she investigates, she finds a diary that reveals a tragic past of a mother and child in that apartment.
Think about your fears. If you're afraid of heights, you could create a story about a skyscraper that has some sort of malevolent force on the top floors. People who go up there start to experience vertigo even more intensely and see strange apparitions that make them lose their balance and fall.
One idea could be to explore the backstories of the monsters in the original Scary Stories. Maybe find out how they became so terrifying and what their motives are. Another could be to continue the story of the survivors from the first book, and see how they are coping with the after - effects of their encounters with the horror.
Some great ideas for interactive scary stories are stories that take place in a creepy old mansion with lots of locked rooms. The reader can pick which room to unlock first. A story about a serial killer on the loose in a small town is also good. The reader can decide how the main character tries to warn the town or hide from the killer. Additionally, a story set in an underground catacomb filled with ancient tombs. The reader can choose whether the character follows a strange noise or tries to find another way out.
A haunted house where every room holds a different nightmare. For example, in one room, the walls bleed and the furniture moves on its own. In another, there are ghostly apparitions of long - dead residents. The protagonist must find a way to escape the house before it consumes them completely.
How about a story based on a cursed object? For example, a beautiful antique mirror. Everyone who looks into it sees a distorted version of themselves, and soon they start having nightmares. Then, they notice that their appearance in real life is slowly changing to match the distorted reflection. The mirror has a dark past and was used in some sort of evil ritual.
