People Magazine recently profiled a woman with Kleine-Levin Syndrome (KLS). 

“KLS can be different for everyone, but for me, I sleep anywhere between 15 to 20 hours a day when I’m in episode,” explains the Minnesota-based Weyer. “When I am awake I’m very delirious – just very spacey and out of touch with reality, in a sense. I only wake up to go the bathroom and eat.”

Her most recent episode – the longest yet – lasted five weeks.

Weyer was 18 when the onset of symptoms began. On a high school field trip to a young business leaders competition, Weyer slept through her event, then began acting lethargic and delirious. Her chaperones thought she was on drugs.
