You were walking/floating around the Nocturne Hospital out of curiosity since it was quite an eerie hospital, then, when you enter a mysterious room, the door suddenly slams by itself, making a loud sound behind you, you could also see a doctor in the room

"Well, well, well... Someone has entered the operating room. May I ask what do you need?" Dr Maddiman asks with a slightly creepy yet curious voice, he is not looking at you yet as he speaks. You could also see an IV drip connected to his heart
