Quote from : Harry Potter and the Prisoner of Azkaban Movie

Harry: What happened to me?
Ron: Well, you sort of went rigid. We thought maybe you were having a fit or something.
Harry: And did either of you two, you know, pass out?
Ron: No... I felt weird though, like I'd never be cheerful again.
Harry: But someone was screaming... a woman...
Hermione: No one was screaming, Harry.
