[sleep] walking.

" There isn't much i'm certain of: it doesn't happen immediately. You'll finish and that will be that, until a moment will come, maybe in a month, maybe in a year, maybe several years. You'll be sick or feeling troubled or deeply in love or quietly uncertain or even content for the first time in your life. It won't matter. Out of the blue, beyond any cause you can trace, you'll suddenly realize things are not how you perceived them to be at all. For some reason, you will no longer be the person you believed you once were [...] Old shelters -television, magazines, movies - won't protect you anymore. [...] Even hallways you've walked a hundred times will feel longer, much longer, and the shadows, any shadow at all, will suddenly seem deeper, much, much deeper...

Then, no matter where you are, in a crowded restaurant or on some desolate street or even in the comforts of your own homes, you'll watch yourself dismantle every assurance you ever lived by. You'll stand aside as a great complexity intrudes, tearing apart, piece by piece, all of your carefully conceived denials, whether deliberate or unconscious.  [...]  the creature you truly are, the creature we all are, buried in the nameless black of a name.

And then the nightmares will begin. "
