A bhoot or bhut is a supernatural creature, usually the ghost of a deceased person, in the popular culture, literature and some ancient texts of the Indian subcontinent.
Interpretations of how bhoots come into existence vary by region and community, but they are usually considered to be perturbed and restless due to some factor that prevents them from moving on (to transmigration, non-being, nirvana, or heaven or hell, depending on tradition).
This could be a violent death, unsettled matters in their lives, or simply the failure of their survivors to perform proper funerals. The belief in ghosts is deeply ingrained in the minds of the people of India across generations and it still persists even in an era of modern technology and scientific development.
The various concepts of ghosts trace their roots in the vast bodies of Hindu mythology, religious texts, literature and folktales. There are many allegedly haunted places in India, such as dilapidated buildings, royal mansions, forts, forest bungalows, burning ghats etc.
Characteristics of bhoots
Bhoots are able to alter and assume forms of various animals at will, but are usually seen in human form. However, their feet often reveal them to be ghosts, as they are backwards facing. As the earth is regarded as sacred or semi-sacred in many traditions of the Indian subcontinent, bhoots go to lengths to avoid contact with it, often floating above it, either imperceptibly or up to a foot above.
Bhoots cast no shadows, and speak with a nasal twang. They often lurk on specific trees and prefer to appear in white clothing.
A particular kind of bhoot, that of a woman that died during pregnancy or childbirth, is known as a chudail (dakini in Nepal and eastern India).
Chudails look like human women, but their feet are turned backwards or other features are turned upside down. They can change their forms at any time. Chudails often try to lure young men at road crossings and fields or similar places.
If a man is enamored of a chudail, it is believed that she will cause his death. There are, however, stories of people living with a chudail, or even marrying one.
In many regions, bhoots are supposed to fear water and steel or iron objects, so keeping those nearby is believed to scare them off. The scent of burnt turmeric is also said to ward them off.
