Ghost ship stories are also quite scary. Picture a ship adrift at sea with no crew in sight. The sails are tattered and the deck is in disarray. Legends say that these ships are cursed. Maybe the crew vanished mysteriously, perhaps due to some evil entity on board. When other sailors come across such a ship, they often feel a chill down their spines, not knowing what kind of horror might be lurking within.
To write kind of scary stories, start with a spooky setting. A dark forest with gnarled trees and thick fog can be a great start. Then, create an element of the unknown. Maybe there's a strange noise that the main character can't identify. Also, use suspense. For example, don't reveal the source of the fear right away. Let the reader's imagination run wild.
Morticians could tell stories about difficult cases they've had. For example, a body that was in a really bad state due to some accident or crime. They may also share stories about families' strange requests during funerals. Like insisting on an open - casket when the body was in a really bad condition. These are the kind of stories that are both scary and strange.
Maybe stories of evil wizards who use the rainbow as a portal to another dimension and bring terror. Or perhaps tales of forbidden love that ends tragically under the rainbow's glow. The possibilities are endless.
Perhaps they'd tell stories about cursed makeup. Like a story of a particular brand of eyeshadow that when applied, makes the person see terrifying visions. Or a story about a powder that gives the user a death - like pallor and then they start being haunted by a spirit.
