Pocong
A pocong, also known as shroud ghost, is an Indonesian and Malaysian ghost that is said to be the soul of a dead person trapped in their shroud. Known in Indonesia as "kain kafan", the shroud is the prescribed length of cloth used in Muslim burials to wrap the body of the dead person. The dead body is covered in white fabric tied over the head, under the feet, and on the neck. According to traditional beliefs, the soul of a dead person will stay on the Earth for 40 days after the death. If the ties over the  shroud are not released after 40 days, the body is said to jump out from the grave to warn people that the soul needs to be released. Once the ties are released, the soul will leave the Earth permanently. Physical appearance. "Pocongs" come in all shapes and sizes, depending on not only the physical appearance of the deceased at the time of death, but also on the state of the corpse's decomposition as well. The "pocong" of a person who has been dead for years would be more skeletal in appearance, whereas the "pocong" of a recently deceased person  would retain a fair resemblance to his or her former self, save for some minor decomposition. Typically, a 'fresh' "pocong" is described as having a pale face and wide open eyes. Multiple sources mentioned a "pocong" with dark face and glowing red eyes, a decayed "pocong" with white featureless eye, and a flat-faced "pocong" with empty eye sockets. Although popular culture often depicts "pocongs" hopping like rabbits due to the tie under their feet rendering the ghosts unable to walk, genuine "pocongs" are said to move around by floating above the ground. This is the distinction that people tend  to look out for when they encounter a 'pocong' in the wild. Behavior. Since not all "pocongs" are the same, it is difficult to pinpoint a specific trait of all "pocongs". Some "pocongs" may show themselves in front of people to relay messages or ask for prayers with no intention to cause harm whatsoever. At the same time, others may not be so docile, actively taking pleasure in frightening people with their grotesque looks. Still, in the main, their behaviors are mostly unpredictable, and people are encouraged not think of them as allies, but rather as supernatural dangers to be  treated with caution. "Pocongs" may form colonies, which could number from a few dozens to a few thousands ghosts for each colony. Despite of this, judging from anecdotal records, most sightings of "pocong" indicate a "lone wolf" style attack, meaning they tend to act independently. It is rare for "pocongs" to work in pairs or in groups to harass humans. As "pocongs" are not bound to the physical world like humans are, they can move freely through solid objects. They have also been observed to teleport almost instantly from one place to another. They are found practically anywhere, from their  final resting places to their former homes. However, banana trees seem to be their preferred spot, it is not uncommon for someone to find a small colony of "pocongs" happily gathering near or around banana trees. Famous story. In some parts of Indonesia there are "pocong" variants that are unique to the places from which they emerged. One of such creatures is known as the "plastic pocong" that haunts the city of Jakarta. The plastic "pocong"'s origin is traced to the purportedly true story of a pregnant woman who was murdered in cold blood by her boyfriend. When an  autopsy was performed on the murdered woman's body, blood kept flowing endlessly from her body even after it was sewn shut. So much blood was pouring out that the hospital staffs were compelled to wrap the corpse in plastic in addition to the traditional shroud, before burying her remains in an undisclosed location. People believed the plastic "pocong" appeared because the murdered woman's soul wished to be freed from her plastic cover. In 2007–2008, the story of an "andong pocong" surfaced in Sidoarjo, East Java, where the ghost was depicted as a lone "pocong" riding a carriage drawn  by a ghostly horse. The arrival of the andong pocong is heralded with a sound of eerie bells. The ghost would knock on the doors of people's homes during the darkest hours of the night, and those who answer to the door would be afflicted by a mysterious illness before dying a few days later. The "andong pocong" story originated from the story of a newly-wed bride who was killed in a freak accident involving a horse carriage, but some people also linked the "andong pocong" to the usage of black magic. "Pocong Merah" or red shroud ghost  is arguably the most feared "pocong" variant due to its violent and dangerous nature, despite of its rarity. It is said to be born out of a person who wished to seek revenge for an unpleasant death, making it more akin to a vengeful spirit often found in many folklores in the West. The red color of this "pocong"'s shroud is associated with the feeling of bitterness, anger, and vengeance felt by the person during the final moments of life. Of all variants of "pocongs", the red "pocong" is believed to be more likely to attack the living on  sight and without provocation. Because of this, many believe the red "pocongs" are kings, or leaders of some sort, of a colony of "pocongs." In the rural parts of Yogyakarta, there is a river known as Code River which is said to be inhabited by a massive colony of "pocongs" numbering in the thousands. The colony itself is led by a very peculiar red "pocong", who lived as an early 20th century local shaman specializing in black magic. According to the story, the shaman's shady lifestyle and practices greatly disturbed the villagers living in the same village. So much  so that one day they decided that they would not tolerate him any longer, and so they hunted him down, murdered him in cold blood, and mutilated his body. The body parts were latter wrapped in large white shroud, which later turned red because of the blood from the shaman's body, and buried somewhere in a pine forest near the riverbank. In death, the shaman swore revenge on the villagers who had slaughtered him in cold blood, and so his vengeful spirit, alongside thousands of "pocongs" he has possessed over the years, has been haunting the Code River to  this very day. Popular culture. Pocongs often appear in religion-based movies or TV serials. In the early 2000s (decade), TV stations in Indonesia purported to capture ghost appearances with their cameras and put the records on a specific show of their own. In these shows, the Pocong appearances could be seen very often, along with the kuntilanak. There was also a movie "Pocong" (2006) directed by Rudy Soedjarwo, which was banned and censored in its French and German DVD versions due to the disturbing, scary, and terrifying scenes. Not long after it was banned, the director created a sequel , less horrible but about the same story, "Pocong 2" (2006). Other titles such as "Pocong 3" (2007), "The Real Pocong" (2009), and "40 Hari Bangkitnya Pocong" (2008) were introduced in the movie series in theaters in Indonesia. The movie "Pocong Jumat Kliwon", directed by successful director Nayato Fio Nuala, began a trend of horror comedy Pocong movies. In 2011 "Pocong is also Pocong", a new horror-comedy featuring Pocong, was made by female director Chiska Doppert, Nayato's former partner. Other recent movies featuring Pocong are "Sumpah, (Ini) Pocong!" (2009), "Pocong Setan Jompo" (2009) and "Kepergok Pocong" (2011). These films  generally share the quality of the pocong playing a role similar to that of the Grim Reaper, in both comedic and dramatic situations.
