The legend of the Nahual is also quite frightening. A Nahual is a shape - shifter, often in the form of an animal by day and a human at night. They are believed to have supernatural powers. In some stories, if a Nahual takes a dislike to someone, they can bring misfortune or even death to that person. People in small Mexican villages used to be very cautious of strangers at night, fearing they might be Nahuals.
There's the story of El Chupacabra. In Mexican folklore, this creature is said to attack livestock, especially goats. It sucks their blood, leaving the animals drained. Many farmers in rural Mexico have reported sightings of a strange, dog - like creature with spines and large fangs that moves very quickly and leaves behind a trail of dead animals with puncture wounds on their necks.
One real scary Mexican story is about La Llorona. It's said that she was a woman who drowned her children in a fit of rage after being spurned by her lover. Now, she wanders near rivers and lakes, weeping and looking for her lost children. People claim to have heard her wailing at night, a truly spine - chilling sound.
