I do not know where you got that information from, but ever since I was little I grew up with people telling me that Aswangs are cannibal-eating beings that live among us. I grew up in Manila and I got to bond with relatives who are from Pangasinan and from Iloilo. So I pretty much know that Aswangs are cannibals. Wherein spirits/ghosts such as the white lady, headless priests, poltergeists…etc, are called Multo.
To top that, supernatural beings are called Engkanto.
