There's no definite answer as to who wrote the very first ghost story. It likely emerged from oral traditions in different cultures long before writing was common.
I'm not sure specifically which 'the very first ghost story' you are referring to. There are many ancient ghost stories from different cultures. It could be about a haunted place, a spirit's revenge, or a strange encounter with the supernatural.
The sense of helplessness is a big factor. In these stories, like in a haunted house scenario, the characters are usually trapped in some way. They can't easily escape the presence of the ghost. Also, the atmosphere created, like dim lighting, cold drafts, and eerie silence broken by sudden noises, all contribute to making the story terrifying. And the idea that the ghost might have some malevolent intent towards the living, that's really scary.
The unknown. In a very scary ghost story, it's often the things that we don't understand or can't see clearly that are the scariest. For example, a strange noise in the middle of the night, or a shadow that moves when there's no one there.
Surviving a dangerous ghost encounter in a very danger ghost story can be tough. First, you need to stay calm and rational. Panicking will only make things worse. Try to find a safe place, like a room with no drafts (since ghosts are often associated with cold drafts). You could also try to communicate with the ghost in a respectful way. Maybe it just wants someone to listen to its story. And don't break any taboos that the story has set up. For example, if the story says not to enter a certain room, then don't. Because breaking those rules might anger the ghost and put you in more danger.
No, they are not real. Ghost stories are just fictional tales made up to scare people. There is no scientific evidence to prove the existence of ghosts or any of the dangerous things that happen in these stories.
A very danger ghost story could be dangerous because of the moral or ethical implications within it. Maybe the ghost is a victim of some great wrong, and the story makes us question our own actions. If it makes us feel guilty or forces us to confront uncomfortable truths, that can be a form of danger. Also, if the ghost story involves some sort of curse that spreads to those who hear it, like in some old folklore, that's really dangerous.
A very good ghost story often has a spooky setting. For example, an old, abandoned house or a fog - covered graveyard. This kind of setting immediately sets a mood of unease.
It could be about a very hungry ghost's experiences, like its search for food or the reasons it is so hungry. Maybe it involves the ghost's encounters in the afterlife while being in a state of extreme hunger.
