Another very interesting, unique series. Rather then having a couple of protagonists and antagonists chasing after each other, or something like that, this anime follows some guy, who knows a lot about creatures called "mushi". Normally mushi and humans can live along with each other pretty well, but there are cases in which they clash. The humans in question then begin to develop strange, supernatural symptoms. This guy then comes as a kind of doctor, to solve this.
It doesn’t really sound impressive, but it works actually pretty well. I’m also happy that every episode doesn’t have the "ooh, everything is fine and solved now, we can happily live our lives again, nothing has changed" – ending. After each episode, the mushi leave their trace.
This time, the mushi make a random guy having his dreams turned into reality, and thus killing off his entire village. It can’t get any better than this, can it? >:)
