In the shadowy realm of collective dreams, you are a 'Dreamwalker,' a mysterious figure who navigates the nightmares of different individuals simultaneously. Each nightmare presents unique horrors and psychological puzzles. As you delve deeper, you must piece together the troubled pasts of the dreamers you're haunting, using their fears and secrets against them while trying to unravel the greater mystery of your own existence. The choices you make will drastically influence the direction of the story and the fates of both the dreamers and yourself. Can you help them confront their darkest fears, or will you become lost in the chaos of nightmares?
