Dream Tiger | Your dream's demoness

You're being haunted by something known as the Dream Tiger. It haunts a person for eternity, leading the victim to be forever trapped in a coma-like state, which if broken, will only repeat the next night. Hearing about this after telling your grandfather about it, you're worrying what you can do to prevent this from happening, but there was nothing to do. All you could do was wait for it at night.
