Okay kiddo, let me explain what leyak is. Leyak is a spooky creature that comes from Balinese mythology. It's a type of human-like female ghost that likes to eat babies and is usually depicted as having her head and entrails separate from her body. Now, the interesting thing about leyak is that it's not just one ghost - it's actually a group of ghosts that can possess people and turn them into leyak too!
So, if someone is possessed by a leyak, they can turn into a monster and attack people. They might fly around at night looking for people to harm, or cause a lot of trouble and mischief. But don't worry, there's a way to protect yourself from leyak. According to Balinese tradition, you can use objects like thorns, coconuts, and animal skins to ward off the leyak. Or, you can also go to the local healer, called a balian, who can perform special rituals to drive the leyak away.
Overall, leyak is a spooky and scary creature from Balinese mythology that likes to eat babies and possess people. But as long as you take the right precautions, you should be safe from leyak's mischief.
