To sum up: Instead of having her walk down the pathway in the Cherry Atrium (a location in the game), the game gliched and stuck Miku in the wall. And because you get a random ghost if you dally too long anywhere, the ghost got stuck with her!

(There's another video with another ghost glitch in Fatal Frame, but it's a small part of it.)
