From The Book of Strange New Things: A Novel by Michel Faber:
Maybe it was simple claustrophobia, although he’d never been claustrophobic before, and had once even bedded down inside an industrial garbage skip with the lid closed over him—and was grateful to have the shelter. He could still remember his sense of wonder when, at some point during the night, the mound of garbage on which he lay started heating up, enveloping his half-frozen body with warmth. This unlikely, unexpected generosity from a non-human agency was an early foretaste of how he would feel in the bosom of Christ.
