Strange things happen in Thoreau: sand starts moving like water, and stones vibrate with life; extinct species return; pine trees cry; fish become trees; men grow grass out of their brains; men, not gods, walk on water; like animals and with them, they also walk on four legs; they talk to fish and birds; birds migrate back to life after they have been seen dead; humans migrate into birds; birds migrate into other birds; humans migrate into other humans; two persons come to inhabit one body; two bodies come to be inhabited by one person.
