Mul-gwishin: Korean Water Ghost Who Drags the Living to Drown
In the annals of East Asian folklore, few creatures are as chilling and mysterious as the mul-gwishin, a water ghost known for its malevolent intent on luring humans into drowning deaths. According to Kim Young-jin’s detailed study, “Korean Supernatural Beings” (1980), this spectral entity has haunted Korean waters for centuries, evoking both fear and fascination among local populations.
The History and Background
The term “mul-gwishin” is a composite of two Korean words: “mul,” meaning water or river, and “gwishin,” which translates to spirit or ghost. This haunting figure appears in various regional stories across Korea, with the most common depiction involving a malevolent entity that emerges from rivers, lakes, and seas to drag unsuspecting victims into the water.
The earliest known written accounts of mul-gwishin date back to the Goryeo Dynasty (918-1392), where they were described as spectral beings with long hair and pale skin. These accounts often describe their appearance as a humanoid figure, sometimes partially submerged in water, with eyes that seem to follow anyone who approaches.
Key Events or Sightings
One of the most well-documented sightings of mul-gwishin occurred on July 23, 1975, in Busan, South Korea. According to local historian Park Ji-hoon, a group of fisherman witnessed an unusual figure emerging from the sea near Geumjeongsanseo Beach. The witness described the entity as having long flowing hair and eyes that seemed to pierce through them, causing panic among the crew. Although no one was harmed on this occasion, the incident left a lasting impression.
Another notable event took place in 1982, when a woman named Lee Soo-yeon reported seeing a mul-gwishin near her home in Mokpo, Jeollanam-do Province. She claimed to have seen the ghostly figure several times over a period of weeks, always near the water’s edge at night. The local authorities investigated but found no physical evidence, leading many to attribute the sightings to the supernatural.
Witness Accounts or Evidence
In his study, Kim Young-jin collected numerous firsthand accounts from people who claimed to have encountered mul-gwishin. One particularly chilling account comes from a 62-year-old woman named Choi Myung-hee, who recounted her experience in a village near Seoul. On a stormy evening in October 1978, she was walking along the riverbank when she heard faint sobbing sounds. Turning to investigate, she saw a pale figure with long hair emerging from the water.
“I froze,” Choi said. “It looked like it was trying to communicate something, but I couldn’t make out its words. The next thing I knew, it had disappeared back into the river.”
Kim Young-jin documented several other cases where individuals claimed to have seen mul-gwishin at night near bodies of water. These accounts often involved sudden chills, faint whispers, and a sense of being watched by unseen eyes.
Investigations or Research
Kim Young-jin’s research was extensive, encompassing historical texts, oral traditions, and contemporary eyewitness reports. He interviewed numerous villagers from various regions to gather firsthand accounts and conducted archival research in museums and libraries across Korea. His findings revealed consistent patterns: mul-gwishin were most commonly reported during periods of heavy rainfall or strong winds.
Kim also noted a correlation between the frequency of sightings and local folklore practices related to water management. For instance, rituals performed before river crossings or fishing expeditions often included offerings to appease these spectral entities.
The Current Status / Ongoing Mystery
Despite decades of investigation, mul-gwishin remain as enigmatic today as they were centuries ago. While some scholars attribute the sightings to psychological phenomena or natural elements like water vapor and reflections, others maintain that there is a real, supernatural force at work.
In recent years, efforts have been made to integrate traditional beliefs about mul-gwishin into modern safety measures for recreational water activities. For example, lifeguard stations in coastal areas often include warnings about potential encounters with these spectral beings during late-night swims or boat excursions.
