Sleep is becoming one of the crisis points of late modernity, as the steady encroachment of the “24/7” plugged-in world only intensifies sleep’s already uncanny nature.[i] To sleep is to slip into a realm of darkness, irrationality, and the supernatural. This realm is not only profoundly opposed to the contemporary illuminated world, but it has always lain uncomfortably close to death. Indeed, the Western way of sleeping has been described as a “lie down and die” model.[ii] To walk or talk while sleeping, moreover, is to act in ways divorced from the world of light and reason, to act without volition and the consent of the mind. The body that acts becomes something other than the person it appears to be; it generates uncanny doubles and evokes the profoundly uncanny uncertainty as to whether, as philosopher Dylan Trigg puts it, “‘I’ am truly identifiable with my body itself.”[iii] Horror films in the twenty-first century in particular have turned to sleep to exploit its inherently uncanny nature and the way it suggests that we are not always in control of who we are and what we do.
