it was suddenly as if , for the briefest of moments , the burden had been lifted , like there was no gravity at all , like he had finally set down the heavy load he 'd been carrying - he knows he should stop this thinking , knows he should get moving , keep himself occupied with simply surviving this place , but he feels like he 's at the bottom of a well , with sunshine and life and escape all miles away , no one to hear him , even if he could call for help .
