The most disturbing element in many true creepypasta stories is the sense of helplessness. For example, in the Slenderman stories, victims often feel like they can't escape his clutches no matter what they do. He just keeps appearing closer and closer.
The psychological aspect is also very disturbing. Take Jeff the Killer. His transformation from a normal boy to a deranged killer due to some unknown event makes you wonder what could drive a person to such extremes. It plays on our fears of the unknown within human nature.
Violence and gore can be extremely disturbing. For example, in stories about real - life serial killers, the way they tortured and killed their victims is sickening. Jack the Ripper's murders in London were full of such disturbing violence.
The most disturbing element is often the senseless violence. For example, in the case of Jeffrey Dahmer, his acts of murder, dismemberment, and even cannibalism are beyond comprehension. It's horrifying to think that a human being could do such things to another.
The invasion of privacy is really disturbing. In these stories, stalkers often know the victim's daily routine, like where they go and what they do, which is a huge breach of personal space.
The most disturbing elements often involve a disruption of the normal order. For instance, objects moving on their own. You know you left your keys on the table and then suddenly they're across the room. Another is when time seems to behave strangely. In some stories, people enter a place and it feels like they've lost hours without realizing it. And of course, the appearance of entities that seem to be in pain or distress, like a moaning figure in a dark hallway, is extremely unsettling as it makes you wonder what kind of torment they might be experiencing.
The feeling of helplessness. For example, if someone is being haunted by a spirit in their own home, they can't just run away easily. They have to live with this terrifying situation, and often there seems to be no way to stop it. It makes you feel really vulnerable.
The violence is often a very disturbing element. In many murder mystery true stories, the victims are subjected to brutal and sometimes sadistic acts of violence. For example, in the case of the Black Dahlia, the mutilation of Elizabeth Short's body was extremely grotesque.
The unknown elements in real creepypasta stories make them disturbing. For example, in stories about supernatural entities like the Slender Man, we don't really know what it wants or how it operates. It just appears and causes chaos, which scares people because it goes against our understanding of the normal world.
The 'Slenderman' is quite famous. It emerged from the concept of a strange, tall figure in the woods. There are tales of hikers feeling watched or having strange encounters in the forest, which might have led to its creation.
'Deliver Us from Evil' is another one. It was based on the casebook of a New York police sergeant who investigated some very strange and seemingly supernatural crimes. The way the movie shows the evil forces at work and the helplessness of the people involved is what makes it so disturbing.
The case of the Manson Family murders is extremely disturbing. Charles Manson led his cult followers to brutally kill several people in 1969. The senseless violence and the fact that it was carried out by a group of people following a madman is truly scary.
