"Then I hear a voice saying: 'Save me...' To my astonishment, the words came from my own mouth." (Room 113)
"You woke from your sleep, high up on a shelf, with porcelain skin and a missing leg." (Room 444)
"You were looking around too much... Your eyes fell out." (Room 666)
And of course... "You knew from the very beginning there was something wrong with this hotel." (Room 555)
