Dark floor(s)

I've never saw a hospital floor so dark. I mean 1 nurse, who is afraid to check on her patients on the Whole floor? And what happened to the cop? He's probably still hiding. Every hospital I've been in has at least 2 security guards and the floor is lit up .it's like this in every scary movie that involves a hospital floor. And no one hears her screaming? Ohhh what's da use...
