In a '5 little ghost story', the number five is likely significant. Maybe the five ghosts each represent a different aspect or emotion. For instance, one could represent fear, another anger, and so on. The location where the story takes place is also crucial. It could be an old, haunted house with creaky floors and cold spots. And the interactions between the ghosts and any living characters in the story would be important elements as well. These interactions could be attempts to scare, or perhaps even to seek help from the living.
If we consider a typical '5 little ghost story', first, the identity of the five ghosts matters. Are they related? Were they victims of some past event? The time period in which the story is set can also be a key element. If it's set in an old - fashioned era, it might add to the spooky atmosphere. Their abilities as ghosts, like being able to pass through walls or make strange noises, are important. Also, any backstories that led to them becoming ghosts, such as a curse or a tragic accident, are essential elements of the story.
Since I don't know the specific '5 little ghost story', generally key elements in a ghost story could include the ghosts themselves, their appearance (maybe they are translucent or have a spooky glow), and the setting which is often a dark and creepy place. The mystery surrounding their existence and what they want is also a key element.
