'In the Department of Mysteries, it's got to be,' Harry whispered. 'I saw that door when your dad took me down to the courtrooms for my hearing and it's definitely the same one he was guarding when the snake bit him.'

Fred swept the hat on to his head, beaming. For a second he merely looked rather stupid; then both hat and head vanished.
MASS BREAKOUT FROM AZKABAN
'Do not interrupt me, Potter,' said Snape in a dangerous voice. 'As I was saying, the vision you had shortly before Christmas represented such a powerful incursion upon the Dark Lord's thoughts -
