Pontianaks are women who died during childbirth, also known as vampiric ghosts. They are described to be paled-skinned with long hair and dressed in white. They usually announce their presence through baby cries. It's said that if the cry is loud, she is far away, but it it soft, then she is near by. Though it is also said that if you hear a dog/wolf howl then she is fare away, but if it's whimpering, she is near by.
