How would you deal with a room full of dead people?

This happened to my college buddy many years ago. He took his girlfriend who was a medical student in the almost deserted hospital where she was supposed to do some late night school related task.

I forgot the exact details but what I could recall clearly is my friend telling me after he dropped her off one of the top floors, he took the elevator down by himself. He overshoots by mistake and when the elevator door opened, he saw rows upon rows of white blanket covered dead bodies in dim light. To make matters worse, the elevator got stuck. For 30 full minutes.

What would you do if that was you?
