Bhut

In Hindu mythology a bhut is believed to be the restless ghost of someone who has died a violent death or committed suicide. According to legend, the bhut has no shawdow and can be detected by the smell of burning turmeric. It is thought that lying on the ground offers protection against it, as the bhut never rests on earth.
Bhuts haunt trees, deserts, abandoned houses, the hearths and roofs of homes, crossroads, and boundaries but never rest on the ground. Rudimentary shrines are sometimes established for bhuts, and when in fear of them a believer will invoke Siva, as he is considered to be their lord.
