Gwisin are a type of spirit or ghost in Korean folklore. They are considered similar to a Yogoe ;, and Mamul ; they are people who have died, not monsters or creatures such as Dokkaebi. These spirits may be found in many places, but most commonly in abandoned buildings, houses, cemeteries, forests, and schools. When a person dies without completing something that they must do, their spirit remains on earth to complete the task before going on to the underworld. However, very strong gwisin do not go tothe underground world if they want to remain on earth, and over time these gain strength.
Legends
There are a lot of legends about Gwisin. Because they are a common form of ghost, children often make them up to scare others or parents tell stories to their children to teach them a lesson. Most legends are about revenge, revenge for their families or about men who cheated on their wives, or murdered the victim. Appearances of Gwisin often occur in high schools, a concept popularized with the release of Whispering Corridors, a Korean horror movie released in 1998.
Physical characteristics
Gwisin are usually transparent, legless and float in mid-air. Female Gwisin usually have white Hanbok which are worn for funerals. They have long, drooping black hair and sometimes they are faceless, depending on their personality. Male Gwisin are somewhat rare, and may appear different.
Appearances
There are many ways they can appear. Gwisin can appear as his/her true self:
They're seen floating, legless or with mist surrounding them.
Standing still, usually facing the person who is witnessing the Gwisin.
Photographs and films.
Dreams and Imaginations.
Reflections.
Other creepy appearances shown in movies, television, videos and comics.
Gwisin can also appear to move things or prank you to get attention:
Gwisin have their own reasons to be on earth, usually that they have unfinished business. Depending on their personality and attitude, their strength and maliciousness can vary. For example, a very calm person who's always nice may not harm or bother other people. She/he will stick to her/his reason. A very aggressive ghost can harm people, even by accident. To become a Gwisin, they must have a very strong urge to stay, or they will have to go to the underground world. Here are some common reasons Gwisin stay on earth.
Wanting to stay longer
Wanting to stay longer with someone
Revenge for someone
Revenge for himself/herself
Rampaging or causing trouble
Unsuccessful birth
Guilt
To prank or trick people
Other jobs to finish
Other reasons
Though they're ghosts, that does not mean their personality and attitude change. If they do not get a person's attention, they can become impatient. For example, they might want attention to send a message to a mortal human being, but if they do not understand or notice, Gwisin may become a little aggressive. Malicious Gwisin who trick or kill people are extremely dangerous, yet no one has sighted one yet. However, people spread rumors about abandoned places, mountains and forests. Schools are another place that ghosts can come out, but it is rare. However, students who committed suicide or were killed do appear, often looking for justice or a chance to graduate.
Development
Gwisin, just like any other ghosts, become stronger as time. They learn to touch things and grab them. Because they are spirits who have no physical human body, their spirit body is transparent and goes through things. After time they learn how to touch and control things.
Sightings
Very old, ancient villages and towns very often have Gwisin. There is at least one sighting of a Gwisin in every place in. Many people claim to have seen or heard Gwisins.
