In Philippine mythology (Bugkalot/Ilongot), Be'tang is a type of ancient spirit. They are highly mysterious, shape-shifting spirits that live in forests and wilderness. Their forms are unpredictable, and written documents describe that a Be'tang can look like a huge deer, a long-tongued horse, a dog, a woman, or any form that may not make sense to humans. They can have small heads and long arms, or have fur and have beast heads, or all of the above. Be'tang spirits are not only strange in appearance, but also they have a weird set of abilities. They can trick humans and bend people’s perception of time. Be'tang spirits can target the mind, even enter a person’s dreams and trap them in it.
