Room 404 - S1.E8

In my dream, I saw room 404 of the Greenwood Hotel engulfed in flames, and lying collapsed in the middle of it, Haku. My unease sends me to the hotel I'd seen in my dream, but when I arrive, I'm told they have no room 404. Unable to erase the fear from my heart, I head up to the fourth floor to investigate and I find something that shouldn't exist - room 404.
