It's the middle of the night. You wake up with a start. There's a presence in the room watching you. You sense that it is evil. But you are paralyzed and powerless. It's your worst nightmare, or is it? This program looks at a strangely common condition called sleep paralysis in which people are dreaming while they are awake and are unable to move. Psychologist Al Cheyne explores what happens to the body during these episodes and tries to explain why the experience is so terrifying. Sleep paralysis appears to be the source of some of our most terrifying myths and legends, and it has inspired artists through the ages. Hags and Nightmares was produced by Michele Ernsting of Radio Netherlands, and airs as part of our international documentary exchange series, Crossing Boundaries.
