For me it was (big surprise) in Amnesia: The Dark Descent in the Choir (The room that's filled with red Silent Hill mist).
I started walking around after I picked up my first piece of Macguffin pie in that room and then I walked up to a bridge. I started hearing the sound that happens when a monster spots you (the creepy high pitched one) so I started running to the door and then as I looked to the right the monster appeared right infront of me in all it's mutated glory just in time for it to kill me! Damn I hate that room.
