Jailangkung is a traditional Indonesian game that can be played by two or more people. To start the game, you need to place a container on a flat surface, like a table or floor, and then put a small object, like a coin or stone, inside the container. Next, you need to tie a piece of string or rope to the container, and then hold the other end of the string in your hand.
The game begins when you and your friends start calling out a spirit or ghost's name, like "Jailangkung." You then move the container using the string, and the ghost or spirit is supposed to move the object inside the container to communicate with you. Many people believe that the ghost or spirit enters the container and uses it to communicate with you, while others believe that it's simply their subconscious mind making the object move.
While this game can be a lot of fun to play, it's often associated with some scary stories, like people claiming to have seen ghosts or spirits while playing. It's important to remember that the game is just a game, and that it's not real. It's also important to play with caution and respect, and to avoid playing in places that might make you feel uncomfortable or scared.
