Welcome to the realm of dreams.

After a nice long day of funkin’ and rappin’, it’s time for a good rest. When you open your eyes, you’re not in Kansas anymore. Here to meet you is a curious fellow, their name is Detra!

…Though you won’t catch them giving introductions. They prefer to get right to the point of things. Why are they here? It seems they want to eat your dreams! Fend them off through the combat of your choice. In this case? Music.
