Sounds in the Hospital?

[=AoD= Captain]

Hadn't thought of this in a while until you brought it up. I recall there being graffiti on the walls of this room as well that caught my attention. I spent a long enough time in the room to study things and hear the sound because the little invisi-bastard in the hall would kill me with one more hit and I had no health doo-dads (this fact making the boss fight a real pain).
