Sundel Bolong is a spooky story from Indonesia about a ghost that looks like a woman with long hair wearing a white dress. This ghost has a big hole in its back (like a big hole in the shape of a big round mouth) and that's why it's called Sundel Bolong. Some people say that this ghost is usually seen near trees, houses or empty fields.
According to the story, Sundel Bolong was once a beautiful lady who went to the dark side and started practicing black magic. Because of her evil ways, she was cursed to become a ghost and to have a big hole in her back. The hole in the back is said to look like a big round mouth because Sundel Bolong usually eats human entrails.
Children are often told about Sundel Bolong by their parents or grandparents, especially as a way to warn them about the dangers of staying out too late or being disobedient. The story is intended to scare children so they will listen to their elders and stay safe.
Though Sundel Bolong is just a ghost story, some people claim that they have seen the ghost in real life. Others argue that these sightings are just rumors or imaginations, and that there is no real danger. However, it's still important to be careful while walking alone at night or in deserted areas, just to stay safe.
