There is something to be said that the truth is stranger than fiction, and hearing creepy accounts have much more potential to terrify us than the darkest fiction.

That’s why the following pages found on Wikipedia will more than likely keep you awake at night, as you mull over the thought that these things actually happened.

What’s to stop them from happening again….

1. The Dyatlov Pass Incident

On February 2, 1959, nine hikers died in mysterious circumstances in the northern Ural Mountains. The nine experienced ski hikers had set up camp for the night on the slopes of Kholat Syakhl.

Investigators were able to determine that the skiers had torn their way out of their tents, from the inside out, fleeing the campsite to escape some unknown threat. The bodies all showed signs of a struggle; Dyatlov had injuries to his right fist as if he had been in a fistfight. One victim had a fractured skull and another was found with brain damage without any sign of distress to the skull. Additionally, one woman’s tongue was missing.

Soviet authorities concluded that an “unknown compelling force” had caused the deaths; access to the region was consequently blocked for hikers and adventurers for three years after the incident. Several possible explanations have been put forward as to the cause of the incident, including an avalanche, a military accident, and a hostile encounter with a yeti or other unknown creature.

2. The Cleveland Torso Murderer

Officially, the Cleveland Torso Murderer killed twelve people however, recent research points to as many as twenty victims. The murders happened between 1935 and 1938 in Cleveland Pittsburgh and Youngstown, Ohio.

The Torso Murderer beheaded and dismembered each of his victims, sometimes also cutting the torso in half; in many cases, the cause of death was the decapitation itself. This made identification nearly impossible, especially since the heads were often not found. The case has never been solved.

3. Unit 731

Unit 731 was a covert biological and chemical warfare research and development unit of the Imperial Japanese Army, that conducted lethal human experimentation during World War II. Thousands of men, women and children interred at the prisoner of war camps, including US POW were subjected to vivisection without anaesthesia.

Between 3,000 and 250,000 men, women, and children died during the human experimentation conducted by Unit 731 at the camp based in Pingfang alone, which does not include victims from other medical experimentation sites, such as Unit 100. Instead of being tried for war crimes, the researchers involved in Unit 731 were given immunity by the U.S. in exchange for their data on human experimentation.

4. Post-mortem Photography

There was a time that humans used to dress up and photograph their dead loved ones. Photographs of deceased loved ones were the norm in America and Europe during the nineteenth and early twentieth centuries. Grieving families would commission postmortem photographs to aid in their grieving and to give a lasting visual reference of a lost loved one. These photographs were usually kept amongst peoples most precious possessions.

5. Spontaneous human combustion

“Spontaneous human combustion” refers to the death from a fire originating without an apparent external source of ignition; the fire is believed to start within the body of the victim.

In 1980, Henry Thomas – a 73-year-old man, was found burned to death in the living room of his council house on South Wales. His entire body was incinerated, leaving only his skull and a portion of each leg below the knee. The feet and legs were still clothed in socks and trousers. Half of the chair in which he had been sitting was also destroyed. His death was ruled ‘death by burning’, as he had plainly inhaled the contents of his own combustion.
