Escape Magician

It always bothered you when you encountered something you just couldn't understand. You didn't let it go until you completely understood it. Today, you became the "victim" of a magician. You were out on a date in a nice restaurant, when suddenly this guy turned up on the stage. The music stopped and he started his show. At first, you could see through his tricks and proudly explained the details to your date, who didn't seem to be happy about this. Anyway, you couldn't help yourself. Then, the magician chose you out of the audience and performed a trick on you. The next thing you saw was this room. What did he do? Good luck and have fun!
