What are the scariest parts of some scary ghost stories based on a true story?

In some stories, it might be the sense of the unknown. For example, when there are unexplained phenomena like objects moving on their own. You don't know what's causing it, and that's really terrifying.

The feeling of being watched is really terrifying. In many true stories, people describe that creepy sensation of eyes on them, but when they look around, there's nothing there. It gives a sense of dread and paranoia. For example, in the story of the old house where the family always felt watched, but they could never find the source.

The unknown and the sense of impending doom. In the story with the truck driver and the strange noises and the apparition, the hitchhiker had no idea what was going to happen next. The fear of the unknown, like whether the driver was a threat or if there were really ghosts, is a very scary aspect in these types of stories.

The scariest part is often the unknown. In many true scary stories, like the haunted house ones, not knowing what is causing the strange noises or apparitions. It could be anything, and that sense of mystery and potential danger is terrifying.

The sense of being watched is also terrifying. In many true ghost tales, people report feeling as if eyes are on them. Like in the Bell Witch story, the family members constantly felt they were being observed by the unseen entity. It makes you feel vulnerable and afraid in your own space. And when it starts to interact, like pulling at your clothes or hair, it's truly horrifying.

The scariest part of the Jefferson Davis Hospital stories is the idea of the lingering pain of the patients. The thought that their spirits are still there, in a place of suffering, is really spooky.

The sense of the unknown in '25 ghost stories' is also quite terrifying. For instance, when a character starts to experience strange events but has no idea what's causing them. It could be a ghostly presence, but they don't know its motives or how to stop it. This lack of knowledge builds up fear.

For the nurse, the movement of the gurney by itself and the sheet on the corpse moving were the scariest. It goes against all logic and normalcy, especially in a morgue which is already a spooky place. It made her feel that there was something supernatural going on.

For me, the scariest is the voices. In exorcism stories, the possessed often speak in strange voices that are not their own, sometimes multiple voices at once. These voices can be guttural, demonic-sounding, and they often say things that are disturbing or full of hatred.

The sense of isolation. Orphans are already alone in the world, and when something scary happens, they have no real family to turn to. For example, in the haunted orphanage stories, they can't just go home to a safe place.
