Creepy Facts About the Human Body

The strangest place on this list may be the one you are sitting in. For a story built on the same skin-crawling feeling, read She Tucks You In.

1. Microscopic mites live in the hair follicles of your face. In a 2014 DNA study, every adult over 18 who was sampled carried at least one species of Demodex mite, which led the researchers to suggest the mites may be universal companions of adult humans. ↳ Thoemmes et al., PLOS ONE (2014)
2. Hair and nails do not keep growing after death. The skin dries and pulls back from them, which only makes them look longer. ↳ Common misconceptions
3. Sleep paralysis leaves you awake but unable to move while falling asleep or waking up, and during an episode people may hallucinate, which often causes fear. Episodes generally last no more than a few minutes. ↳ Sleep paralysis
4. Exploding head syndrome is a real, harmless sleep phenomenon: as you drift off or wake up, you hear a loud noise like an explosion or thunder that is not there. ↳ Exploding head syndrome
5. People with Cotard’s syndrome, sometimes called walking corpse syndrome, hold the delusional belief that they are dead, do not exist or are rotting. ↳ Cotard’s syndrome
6. In alien hand syndrome, a person’s hand seems to act on its own. It may reach for and handle objects against the person’s wishes, sometimes so stubbornly that the other hand has to restrain it. ↳ Alien hand syndrome

Creepy Facts From History

Real history has a way of outdoing fiction. If these send you looking for older ghosts, try our famous ghost stories or the scary urban legends, retold with their origins.

7. In the summer of 1518, somewhere between 50 and 400 people in Strasbourg danced uncontrollably for weeks. Nobody knows exactly why; the most popular explanation is stress-induced mass hysteria. ↳ Dancing plague of 1518
8. Artists once painted with mummies. The pigment “mummy brown” was made from the flesh of mummies mixed with white pitch and myrrh, and suppliers only stopped offering it around the middle of the twentieth century. ↳ Mummy brown
9. In Europe, thousands of Egyptian mummies were ground up and sold as medicine. ↳ Medical cannibalism
10. Fear of being buried alive was common enough that many “safety coffins” were patented in the 18th and 19th centuries. Most designs let the occupant signal the surface, often by pulling a cord attached to a bell. ↳ Safety coffin
11. In the early 19th century, families in Britain locked heavy iron cages called mortsafes over fresh graves to stop body snatchers from stealing corpses for anatomy schools. ↳ Mortsafe
12. In 1828, William Burke and William Hare murdered sixteen people in Edinburgh and sold the bodies for dissection. After Burke was hanged, his own corpse was dissected, and his skeleton is still displayed at the Anatomical Museum of Edinburgh Medical School. ↳ Burke and Hare murders
13. The Tollund Man, found in a Danish bog in 1950, was so well preserved that he was mistaken for a recent murder victim. Radiocarbon dating places his death between 405 and 380 BCE, and the noose he was hanged with was still around his neck. ↳ Tollund Man
14. The famous body casts at Pompeii are not bodies. Excavators found hollow spaces in the volcanic ash left by decomposed victims of Vesuvius, and in the 1860s Giuseppe Fiorelli began filling them with plaster to recreate their final poses. ↳ Pompeii

Creepy Facts From Nature

Some of the most disturbing behavior on Earth is perfectly natural. For a fictional forest with its own rules, read The Cabin That Knows Your Name. For thirty more from the animal kingdom, see our creepy animal facts.

15. The zombie-ant fungus makes infected ants leave their nests, climb to a spot suited to the fungus, and clamp their jaws onto the underside of a leaf, where they stay after they die. ↳ Ophiocordyceps unilateralis
16. The emerald cockroach wasp stings a cockroach, chews off half of each antenna, then leads the still-living roach to its burrow by an antenna, like a dog on a leash, to serve as food for its larva. ↳ Emerald cockroach wasp
17. The tongue-eating louse enters a fish through its gills, clamps onto its tongue and cuts off the blood supply until the tongue falls off. Then the parasite takes the tongue’s place. ↳ Cymothoa exigua
18. Rats infected with the parasite Toxoplasma gondii show less aversion to cat urine, a change that may make them more likely to be eaten by cats, the only known hosts where the parasite can reproduce sexually. ↳ Toxoplasma gondii
19. Bone-eating “zombie worms” of the genus Osedax settle on sunken bones and secrete acid to dissolve their way inside to reach the fats. ↳ Osedax
20. The titan arum, nicknamed the corpse flower, blooms rarely and briefly and gives off a powerful smell of rotting flesh to attract carrion insects. ↳ Amorphophallus titanum
21. Hagfish defend themselves by releasing huge amounts of slime from glands in their skin. ↳ Hagfish
22. The chemistry of Tanzania’s Lake Natron is known to calcify the bodies of animals that die in it, leaving stiff, stone-like remains. ↳ Lake Natron

23. The Catacombs of Paris hold the remains of more than six million people, moved from the city’s overflowing cemeteries starting in 1788. They have been open to public visits since 1874. ↳ Catacombs of Paris
24. The Sedlec Ossuary in the Czech Republic is estimated to contain the skeletons of 40,000 to 70,000 people, many arranged into decorations, including a chandelier of bones. ↳ Sedlec Ossuary
25. Beneath a church in Rome, the Capuchin Crypt contains the skeletal remains of 3,700 bodies believed to be Capuchin friars. The order says the display is a reminder of mortality, not meant to be macabre. ↳ Capuchin Crypt
26. A coal mine fire has burned beneath Centralia, Pennsylvania, since 1962. The town’s population fell from 1,000 in 1980 to five in 2020. ↳ Centralia, Pennsylvania
27. On Mexico City’s Island of the Dolls, in the canals of Xochimilco, hundreds of weathered dolls hang from the trees. Local legend says the island’s reclusive former owner, Don Julián Santana Barrera, hung them for a girl who drowned nearby, though no evidence of the girl has ever been found. ↳ Island of the Dolls
28. More than 200 bodies remain on Mount Everest because recovering them is too dangerous. One, known as “Green Boots,” served as a landmark on the northeast ridge route until it was moved in 2014. ↳ Mount Everest

The mites on your face. Look in a mirror. You cannot see them, but they are almost certainly there. Microscopic mites called Demodex live in the hair follicles of the human face. In a 2014 DNA study, every adult over 18 who was sampled carried at least one species. The researchers suggested the mites may be universal companions of adult humans. So they are not a sign that anything is wrong with you. They are simply there, on nearly everyone, too small to see, living in your face while you read this. Try not to think about it tonight. ↳ Thoemmes et al., PLOS ONE (2014)

The bell above the grave. In the 18th and 19th centuries, the fear of being buried alive was so common that inventors patented “safety coffins”. Most designs gave the person inside a way to signal the surface, often a cord running from the coffin up to a bell above the grave. Think about what that means. Someone, somewhere, believed it was likely enough that a person might wake up underground that they built a way to ring for help. And families paid for it. Next time you walk past an old cemetery, listen. ↳ Safety coffin

The ant that is no longer itself. In tropical forests, a fungus infects carpenter ants. The infected ant leaves its nest, climbs to a spot that suits the fungus, and clamps its jaws onto the underside of a leaf. Then it dies there, still holding on. The ant did all of this itself, but not for itself. They are known as zombie ants. The fungus does not need the ant to understand where it is going. It only needs the ant to keep climbing. ↳ Ophiocordyceps unilateralis

The man in the bog. In 1950, two men cutting peat in a Danish bog found a body so well preserved that they thought he was a recent murder victim. He still had the noose around his neck. Radiocarbon dating told a different story: he had died between 405 and 380 BCE, more than two thousand years earlier. The bog had kept his face so perfectly that the people who found him thought he had died recently. Today he is known as the Tollund Man. ↳ Tollund Man

The landmark on the mountain. More than 200 bodies remain on Mount Everest, because bringing them down is too dangerous. One of them became so familiar to climbers on the northeast ridge route that it had a nickname, “Green Boots”, and was used as a landmark, a way of knowing how far you had come. It stayed there for years, until it disappeared in 2014, presumably removed or buried. Climbers passed it on the way up. And on the way down. ↳ Mount Everest

The summer Strasbourg danced. In the summer of 1518, people in Strasbourg began to dance and could not stop. It went on for weeks. Estimates of how many danced range from 50 to 400. Nobody knows exactly why it happened; the most popular explanation is stress-induced mass hysteria. Imagine a street full of people dancing for days, exhausted and afraid, unable to say why they could not stop. Historians are still arguing about it more than five hundred years later. ↳ Dancing plague of 1518

How We Chose and Checked These Facts

We left out anything we could not trace to a reliable source, including some of the most shared “facts” online. Each entry links to the page we checked it against on October 18, 2026: usually a Wikipedia article that cites the original research, or the study itself. Where a source gives a range (the dancing plague’s 50 to 400 dancers, Sedlec’s 40,000 to 70,000 skeletons) we kept the range rather than picking a dramatic number.

We also avoided recent tragedies involving private people. The historical crimes included here are well over a century old and thoroughly documented. If you spot an error, tell us through the contact page and we will correct it.

Turning a Creepy Fact Into a Story

Facts like these make excellent story seeds because the reader already believes them. Take one detail, such as a bell above a grave, a mite you cannot see or a landmark that is also a body, and ask what would happen if it went one step further. Our list of scary story ideas works the same way, and the guide on how to write a horror story explains how to turn a single unsettling rule into a full plot.

Short on time? A creepy fact also makes a natural first line for a two sentence scary story: state the fact plainly, then let the second sentence make it personal.
