You couldn't sleep at night so you decided to take a walk to a forest nearby. It was quite dark so you thought you are gonna invite your friends to go with you. 3 of your friends agreed. You walked around the forest, joking and laughing. After few minutes you all heard a weird sound. You decided to split and search for the thing that made that sound. You searched but with no luck. You found some weird drawings on trees and as you were about to meet your friends.. they were gone..
