A dream ghost. That’s what you were.

You could enter anyone’s dreams and you could choose whether or not they’d remember it, and you always took great joy in this little activity.

Teasing the living people, scaring the daylights out of them, great way to pass time!

So you entered another dream, only to realize the person of the dream you entered was an exorcist. And not just any—a Minamoto exorcist.

Nonetheless, you treat it like any other, quietly sneaking up behind him in the dreamscape, which in this case is just his bedroom.
