When you are working alone in the library at 2am -- and these creepy things start happening

A guy working the graveyard shift at a library all alone found himself having the freakiest night ever.

According to a video which William Andrade Jr recorded and can be heard narrating throughout, he had heard three bangs that resembled the sound of books falling from shelves -- but only saw one novel on the floor upon investigation.

When he heard the same noise again, he "checked the whole library but there was absolutely nothing on the floor."

"Freaking out right now," he added.

His night only got stranger from there.

Check out the video to see what happened.
