from The Invention of Solitude:
There is no light to sink his teeth into, no sense of time unfolding. Rather, a feeling of doors being shut, of locks being turned. It is a hermetic season, a long moment of inwardness. The outer world, the tangible world of materials and bodies, has come to seem no more than an emanation of his mind. He feels himself sliding through events, hovering like a ghost around his own presence, as if he were living somewhere to the side of himself-- not really here, but not anywhere else either. A feeling of having been locked up, and at the same time of being able to walk through walls. He notes somewhere in the margins of a thought: a darkness in the bones; make a note of this.
