A Dream + Mama + Naruto + Clones + A Video Game = ?

I did not voice record my dreams when I woke up to use the bathroom, and so I barely can remember part of the end of my last dream from last night; and this dream seemed to be inspired by the movie Mama, which I watched before going to sleep, and the Japanese anime series Naruto.

I can not remember the parts of the dream that were inspired by the movie Mama, but I do remember being inside a windowless building in a library-like room with many bookshelves with books.
