Jenglot, mysterious creatures of Indonesia

Jenglot, mysterious creatures of Indonesia is a strange phenomenon began to spread in the community in 1997an year. Jenglot is an object / creature (I am puzzled to determine whether the object or creature) is a small human form with a body no more than 12 cm and long hair, sparse and stiff through the legs, and her nails long.
Jenglot believed to society is as a person who has the magic of science in the past (maybe a hermit so) who died, but was rejected by the earth, so that his body was not destroyed but shrinks to a shape like jenglot. Means believed that "jenglot it used to be a man" ...
If examined from a scientific aspect, it is clear there can be no such phenomenon. The human body would decompose if buried in the ground.
Even more strangely again, usually jenglot appear suddenly or at the time of the sakti (shaman) to high-level mystical rituals.
Then according to the sacred, jenglot must be fed blood, one drop of blood each period (how many weeks / days, I am less tau). Uniquely, every time jenglot not given appropriate conditions of blood there would be a misfortune that had befallen the people around.

After the the scientific examination results were declared jenglot no bone structure. Results rontgent witnessed dozens of journalists, medics, student practice, it only shows the form of a buffer-like structure from head to body. Also visible is also a network of four nails and no teeth remaining.
