We spend about a third of our lives sleeping, but scientists still aren’t entirely sure why. After Dark: While You Were Sleeping examines the unknown and other-worldly dimensions of sleep, darkness and night. You’ll wander through somnabulant filmscapes, examine a curious case of nyctalopia (night blindness), and cozy up to an experimental bunk bed chat. After Dark is included in the price of admission to the Exploratorium.
