Speaking of odd phenomenon, can you all explain this short apparition video from one of the Ghosthunters episodes from the first season?

If you've never seen the show (which I hadn't until about a week ago), all of the first season is also available on YouTube, including the full episode of the video above (the Eastern State Penitentiary). I admit, I'm addicted now.
