"Let me give you some advice, my dear young friend. Indeed: allow me to warn you, in all seriousness, that if you wish to leave these rooms you will not have the opportunity to sleep anywhere else in the castle. It is an old castle, it contains many memories, and there are bad dreams for those who sleep there carelessly. Be careful! If you have to fall asleep, now or at another time, or are about to do so, hurry to your room, or to these rooms, because only in this way will you rest in safety."
