" It’s one of those unpleasant opioid feverish half-sleep states, more a fugue-state than a sleep-state, less a floating than like being cast adrift on rough seas, tossed mightily in and out of this half-sleep where your mind’s still working and you can ask yourself whether you’re asleep even as you dream. And any dreams you do have seem ragged at the edges, gnawed on, incomplete. "

― David Foster Wallace , Infinite Jest
