By our best guesses, Halloween may be older than Christianity. In those days, it was a Celtic pagan festival called “Samhain,” a time when the barriers between the land of the living and the dead blurred. Those ancient “creepy rituals” set the stage for the spooky holiday we know today.
Why These Creepy Rituals Matter
Understanding the dark customs gives us a glimpse into how our ancestors faced the unknown, and why some of these practices still echo in modern celebrations.
1 Child Sacrifice
In the earliest days, Samhain may have involved child sacrifice. Irish legends tell of gods demanding offerings during the festival. One tale claims people had to surrender two‑thirds of everything they owned at winter’s start—including corn, milk, and their children.
Another source, a Christian monk, describes a place called Mag Slecht where an idol to the deity Cromm Crauch stood. According to his account, this altar was used to sacrifice children during Samhain.
“They slew their hapless firstborn with much wailing and peril,” the monk writes, “to pour their blood around Cromm Crauch.”
2 Dressed
It wasn’t just the line between living and dead that blurred. Samhain also became a time to blur gender lines. By the mid‑19th century, most door‑to‑door groups on Halloween were men dressed as women—called “hags” in Wales.
These hags would knock on doors asking for food or hospitality. If a home was particularly dirty, the men‑in‑women’s clothing would wander inside, start sweeping, and hum “mum‑m‑m,” acting like a disapproving wife.
3 People Dressed Up As The Dead
Costumes were part of Samhain, but they weren’t superhero capes. Folks painted their faces black and fashioned disguises from straw, hoping the wandering spirits would think they were one of the dead.
Others used the skins of freshly slaughtered animals. The festival coincided with massive animal slaughter for winter stores, and the first sound of the celebrations was the squeals of dying pigs. To avoid the touch of the dead, people turned animal skulls and hides into demonic‑looking outfits.
4 The Black Sow
Fire played a central role in Samhain. In Moray, boys would go door‑to‑door begging for “peat to burn the witches.” They’d build a massive fire, lie as close as possible without being burned, and let the smoke billow over their bodies. Their friends would then leap over them, believing the ritual granted magical protection.
In parts of Wales, participants would sprint away from a fire, fearing a creature called the Black Sow would claim the slowest runner. Earlier versions of the rite allegedly involved catching the slowest person, loading them with the year’s accumulated evils, and throwing them onto the bonfire as a human sacrifice.
5 People Drank Heavily
One major Samhain tradition was getting as drunk as possible. The festival marked the final harvest before winter, leaving a surplus of grain that was turned into alcohol. Since refrigeration didn’t exist, the excess had to be used or wasted.
Stories of extreme drunkenness are woven into every ancient Irish tale about Samhain. Legends like “The Intoxication of the Ulstermen” use a night of heavy drinking as the catalyst—or even the entire focus—of the narrative.
6 The Creatures Of The Cave Of Cats
The most dangerous spot during Samhain was Oweynagat, the Cave of the Cats—a narrow hole dug into a hillside. Legend says the Fairy Queen stopped there centuries ago, and her maidservant begged to live there, leading to the cave becoming overrun with malevolent spirits.
Medieval notes claim people saw monsters crawl out of the cave. One account describes a woman emerging each year to take nine of the best animals from every herd. Other tales speak of strange beasts and demonic cats released during Samhain to attack the town below.
7 Fairies Kidnapped People
During Samhain, fairies left their homes to roam the mortal world, but these weren’t the friendly Tinkerbells of today. Led by the King of the Dead, they rode storm clouds with an army of hellhounds, gathering the newly dead.
On Samhain, the fairies were less selective, sometimes pulling living people along with the deceased and dragging them to the afterlife. To avoid this fate, folk stayed far from fairy mounds, fearing a stray could snatch them and pull them down into hell.
8 Fortune‑Telling
Samhain was a prime time for calling upon spirits to predict the future. Various strange “spells” were performed to reveal whether prosperity or misfortune lay ahead.
One innocent‑looking rite had girls hiding beside a neighbor’s house, filling their mouths with water, and holding a pinch of salt in each hand while eavesdropping. The first name of an unmarried man they heard was believed to be the one they would marry.
Another involved men opening barn doors and miming the lowering of corn three times. After the third gesture, a spirit would pass through, taking the appearance of the occupation the participant would hold in adulthood. Boys were warned to remove the hinges from the doors, or the spirit would linger and torment them.
9 The Rise Of The Dead
Legend says Samhain opened the doors between the world of the living and the dead. Spirits of departed loved ones could wander out, sometimes trying to find their way back home.
In some regions, people showed compassion by leaving food outside doors to feed wandering ghosts or by keeping doors ajar and preparing a place for the dead to rest.
Not all spirits were benevolent. One Irish tale recounts a creature called Aileen emerging from the otherworld to burn the town of Tara to the ground each Samhain. In fear of such entities, some communities locked their doors tight, refusing to step outside.
10 The Ritualistic Murder Of Kings
In Irish bogs, archaeologists have uncovered bodies perfectly preserved by a thick layer of black peat. Their faces, hair, and even the fine details of their skin remain intact after centuries.
These aren’t random burials. The clothing and grooming suggest the victims were members of the ruling class, fitting legends of a ritualistic king murder performed on Samhain.
When a year was plagued by famine or disease, the community would blame the king. The failed monarch would be sacrificed, replaced, and his body discarded into a bog as part of the ceremony.
