Macy Halford plucks out a few choice paragraphs from philosopher Jean-Luc Nancy's The Fall of Sleep:
By falling asleep, I fall inside myself: from my exhaustion, from my boredom, from my exhausted pleasure or from my exhausting pain. I fall inside my own satiety as well as my own vacuity: I myself become the abyss and the plunge, the density of deep water and the descent of the drowned body sinking backward. I fall to where I am no longer separated from the world by a demarcation that still belongs to me all though my waking state and that I myself am, just as I am my skin and all my sense organs. I pass that line of distinction, I slip entire into the innermost and outermost part of myself, erasing the division between these two putative regions.
Sometimes a great image and a poseur alert are very close together.
