I grew up listening to stories about Pinoy "elementals" -- like tikbalang, kapre, manananggal, aswang and dwende/nuno. Such stories are already part of the Filipino culture and have been passed from generation to generation. Some stories were used by elders to scare young children from going out at night.
Please check out my Buhay Pinoy article: Kuwentong kababalaghan: Manananggal, kapre atbp . The actual feature is written in Filipino (without translation).
