“Clearly dreams do something for us,” writes Michael W. Clune. “If not, why would evolution have endowed us with the capacity?” In this essay, Clune explores the fascinating world of dream engineering via a device called the Dormio, which enables a person to shape the images that appear during hypnagogia, the transitional stage between wakefulness and sleep.
