"Sleeping Beauty Syndrome" may sound like a problem for a Disney princess, but life is no fairy tale for a real woman suffering from the condition. Beth Goodier was diagnosed with Klein-Levin syndrome, which causes her to fall asleep for months at a time. The 22-year-old has been living with it for the past 5 years. She only takes short walks during her sleep episodes, which leave her feeling weak. The condition also alters her behavior and reduces her understanding of the world.
