There was a man who was certain that his reflection in the mirror was an impostor trying to take over his life. He smashed all the mirrors in his house and avoided any reflective surfaces. His mental state deteriorated rapidly as this delusion consumed him. The family had to constantly monitor him to prevent him from hurting himself, and it was a very difficult situation for everyone.
I've heard of a story where a person discovered they were related to someone involved in a really heinous crime. Just the thought of having a connection like that was very disturbing for them.
A prison had a rule where inmates were not allowed to speak during meal times. If they did, they would be put in solitary confinement. One inmate accidentally made a noise while eating and was sent to that dark, lonely cell for days. It was a really disturbing situation.
There's a story about a sociopath in a high school. He targeted the loneliest students. He would befriend them, gain their trust, and then start spreading their darkest secrets around the school. He made some students so depressed that they considered suicide. It's really a horror story as it shows how cruel a sociopath can be to the vulnerable.
I heard of a story where a patient got an infection from a dirty surgical instrument. The infection spread rapidly and caused the patient to be in constant agony. It took a long time and a lot of strong antibiotics to finally get the infection under control. This shows how crucial strict hygiene is in medical settings.
I've heard of a prison guard who walked into a cell to find it covered in strange symbols drawn in blood. The inmate in that cell just stared at him with a blank look, which sent chills down his spine.
I heard that during some fan events, there were arguments that turned physical over which character was more important or which storyline was better. It was really disturbing to see that a fandom which was supposed to be about enjoying a fun anime could lead to such aggression. People were shouting and pushing each other, all because of differences in their love for Hetalia.
The most disturbing one I heard was when a family thought they were renting a house. They paid the deposit and first month's rent. But when they showed up on moving day, the 'owner' had already rented it to someone else and refused to return their money. They were left homeless and out of a large sum of money.
In a summer camp deep in the mountains, there was a story of a group of campers who found a dead body in the woods. They were out on a nature walk when they stumbled upon it. It was an old hiker who had probably passed away from natural causes, but for the young campers, it was a horrifying discovery. They had to wait for the authorities to come, and the whole experience haunted them for a long time. It was a really disturbing encounter that no one expected at a summer camp.
A friend told me about a person she thought was her friend. This 'friend' would steal small things from her like hairbands or earrings and then deny it. But she would later find those items in the 'friend's' bag. It was really disturbing.
One horror story is about a person with paranoid schizophrenia who was convinced that there were hidden cameras everywhere in their house. They tore apart the walls, looking for these non - existent cameras, creating chaos and destruction in their home.
