Exulansis: “the tendency to give up trying to talk about an experience because people are unable to relate to it—whether through envy or pity or mere foreignness—which allows it to drift away from the rest of your story, until it feels out of place, almost mythical, wandering restlessly in the fog, no longer even looking for a place to land.” (John Koenig, The Dictionary of Obscure Sorrows)

How often in the overflowing streets
Have I gone forwards with the crowd, and said
Unto myself, ‘The face of every one
That passes by me is a mystery.’

William Wordsworth, The Prelude (1805), 10.595-98
