You and some of your friends had just walked through the door to the escape room and you of course chose one whit live actors and also a horror themed one.

you suddenly noticed that your friends hasn't said anything to you or made any noises so you turned around and they weren't there and you intensely knew that they didn't go through the door and you began to panic and ran into a random room but you heard some noises and looked around and froze when you saw a man crawling on the roof.
