This morning three girls came to me to report that last night at 1am one of them heard a noise like the door being fiddled with and then suddenly a man shadow appeared in the room in the dark. They all three started screaming and the man hastily ran away. So I called the manager to investigate and look at the cameras etc for their floor. It turns out it was the receptionists fault. He gave the wrong key to a new guest arriving late who was as shocked as the girls were to find his room occupied, so ran back to reception and was given the correct floor and key. The girls are much relieved.
