Ghosts of the dead, lost souls expelled by Gendui Lanyut, who
work upon the living through the agency of rain, heat, in mountains and lakes, rocks and trees.
The hantu kĕmuk
has a globular body like the fruit of the wax-gourd ("kundor"). It is pallid in colour, and chases people at sight, rocking itself after them, and making a noise which sounds like "nuh-uh-uh-uh." When it enters people they get "all abroad" and feverish, and little by little it "steals their life."
