Harry decides to use the invisibility cloak to sneak into the restricted section of the library during the night and do some more research on Nicolas Flamel. Once of the books starts screaming after he opens it, and Harry runs out of the library and hides in an abandoned classroom while Filch prowls around. Inside the classroom, Harry discovers a massive mirror that is ornately decorated and carved with a strange inscription: “Erised stra ehru oyt ube cafru oyt on wohsi.” Harry looks in the mirror and is terrified when he does not see his own reflection. Instead, he sees several people smiling and waving at him. One of the figures is a very pretty woman with striking green eyes, and Harry realizes that he is looking at his mother.
