The Batibat is a vengeful demon found in Ilocano folklore. In Tagalog folklore, the creature is called Bangungot. These demons were blamed as the cause of the fatal nocturnal disease called bangungot. A batibat takes the form of a huge, old, fat woman that resides in trees. They usually come in contact with humans when the tree in which they reside is felled and made into a support post for a house. This causes them to migrate into holes found in the post. The batibat forbids humans from sleeping near its post. When a person does sleep near it, the batibat transforms to its true form and attacks that person. It sits upon the chest of its victim until he suffocates. To ward off the batibat, one should bite one's thumb or wiggle one's toes. In this way, the person will awaken from the nightmare induced by the batibat.
The creature appears in the fifth episode of the Netflix series Chilling Adventures of Sabrina, played by Megan Leitch. This version of Batibat is depicted in the episode "Dreams in a Witch House" as a demon that is unintentionally released by Sabrina Spellman from a puzzle belonging to her father. Trapped in the house, Batibat proceeds to vengefully torture the Spellman family by inducing their dream states. The demon preys on their nightmares in the hopes that one of them will free her from the house, but is ultimately thwarted by Sabrina and Mary Wardwell / Madam Satan.
