Let me advise you, my dear young friend — nay, let me warn you with all seriousness, that should you leave these rooms you will not by any chance go to sleep in any other part of the castle. It is old, and has many memories, and there are bad dreams for those who sleep unwisely.

Life is a nightmare that prevents one from sleeping.

Broken dreams are bad enough. But the dream that has no hope … the dream that is doomed long before it’s broken, that’s the worst of all.

All men dream: but not equally. Those who dream by night in the dusty recesses of their minds wake in the day to find that it was vanity: but the dreamers of the day are dangerous men, for they may act their dream with open eyes, to make it possible.

In the morning you wake from one bad dream and another begins.

Then I reminded myself that all intelligent children suffer bad dreams.

I could hardly get to sleep for dreaming of revenge.
