It's because the door hasn't been closed yet that the nightmares still find their way in.

If we didn't have nightmares, we wouldn't wake up every morning chasing our dreams.

Even if she be not harmed, her heart may fail her in so much and so many horrors; and hereafter she may suffer--both in waking, from her nerves, and in sleep, from her dreams.

I still get nightmares. In fact, I get them so often I should be used to them by now. I'm not. No one ever really gets used to nightmares.

Thus fortified I might take my rest in peace. But dreams come through stone walls, light up dark rooms, or darken light ones, and their persons make their exists and their entrances as they please, and laugh at locksmiths.

It is when one begins to lose the consciousness of freedom, and when the idea of necessity enters the world at all, when there is any hurry or strain anywhere, a letter to be written or a train to catch, when you have got to work, to make the horses of the dream gallop, or to make the rifles go off, that the dream is declining, and turning into the nightmare, which belongs to the poorest and most vulgar class of dreams.
