In Japanese folklore, an ikiryō is the living soul of a person that leaves the body and wanders. Unlike a ghost, which manifests after someone’s death, an ikiryō comes into being when a person is alive but harboring extreme emotions, such as jealousy or resentment. These intense feelings can cause a part of their soul to split off and haunt someone else, often causing sickness or misfortune. Seen as a foreboding presence, the ikiryō isn’t always malevolent, though its appearances are rarely a good sign.
The snallygaster was a bizarre creature feared by early settlers in colonial America, especially in Maryland. Described as a dragon-like beast with the body of a bird and tentacle-like appendages, it was said to swoop down from the skies, shrieking and terrorizing farmers.
Its rumored sharp teeth and lethal claws could easily tear livestock apart. Legend has it that a seven-pointed star could ward it off, so barns in the area were often marked with the symbol as a form of protection. Sightings of the snallygaster have faded, but its legacy continues in regional folklore.
The chullachaki, or "uneven-footed one," is a forest spirit known in the Amazonian lore of Peru and Brazil. Often depicted with one human foot and one animal foot, this mischievous being is said to lead people astray in the jungle, causing them to get lost. Known for its shapeshifting ability, it can disguise itself as a friend or family member to lure wanderers deeper into the forest. Some locals claim the chullachaki can be friendly, but most steer clear of it, fearing its tricks and the mysteries it hides.
The Mare is a Norse and Germanic folklore creature believed to cause nightmares by sitting on a sleeper’s chest. Unlike a ghost or demon, the Mare is seen as a spectral entity that travels through keyholes or cracks to torment its victim. While a person sleeps, the Mare sits on their chest, making breathing difficult and filling their mind with terrifying visions. Some believe the Mare to be the root of the term "nightmare," giving a tangible form to the unsettling feelings that come with bad dreams.

In Brazilian folklore, the boto is a dolphin spirit known to transform into a handsome young man, especially at night, to seduce women. This myth centers on the Amazon River dolphin, a pink dolphin native to the region. Often appearing at local festivities, the boto is said to be dressed in white and easily charms the townsfolk, disappearing back into the water by morning. The legend holds such power that "Boto" remains a common excuse for mysterious pregnancies, with the dolphin spirit’s reputation adding a surreal twist to rural Brazilian culture.
The nian is a monstrous creature in Chinese folklore, believed to have a lion-like appearance and a hunger for people, particularly children. Legend states that the monster would emerge from hiding every Lunar New Year to wreak havoc on villages. People discovered that loud noises and the color red scared the nian away, which inspired the firecrackers, red lanterns, and red clothing now associated with Lunar New Year celebrations. Though rarely mentioned today outside of festivities, the nian remains a symbol of warding off evil.
In Serbian mythology, the bukavac is a six-legged beast with long horns, said to reside in lakes and rivers. Emerging from the water at night, it emits terrifying screams and strangles anyone it encounters.

Tales of this creature continue to circulate in rural areas, often as part of local customs and storytelling sessions, inciting both curiosity and caution among listeners.
In Central American folklore, especially in El Salvador, the siguanaba is a frightening spirit who appears as a beautiful woman to lure men into danger. Legends say that she preys on unfaithful or careless men, leading them deep into the forest before revealing her horrifying face—a skull or a monstrous visage. The siguanaba is considered a cautionary tale warning men against immoral behavior while reinforcing respect for nature, as those who encounter her often lose their way or become disoriented.
The coco, also known as El Cucuy in some Latin American countries, is a terrifying figure used to frighten children into good behavior. Traditionally described as a shapeless monster hiding under beds or in closets, the coco comes to take away misbehaving children. Spanish lullabies even mention the creature, warning children that the coco is watching. Unlike most folklore beings, the coco is deeply ingrained in family culture, acting as a dark reminder to children to stay obedient or face mysterious consequences.
In Philippine folklore, the tiyanak is a vampiric creature that disguises itself as an abandoned baby crying in the woods. When unsuspecting travelers come to rescue the child, it reveals its true form: a tiny demon with sharp teeth and a hunger for human flesh. The legend of the tiyanak is said to be a caution against straying too far from home or venturing into dangerous areas, though it has also evolved into an eerie tale warning of trickery and deception.
