(Scroll down for video) A girl in the U.S. is a real life sleeping beauty, according to reports.
The Pennsylvania teenager slept for 64 days from Thanksgiving to January, her longest episode yet of sleeping.
Nicole Delien, 17, struggles with a rare sleep disorder called Kleine-Levine, or "Sleeping Beauty Syndrome.”
During her periods of sleep she can wake up in a state of confusion for short periods of time to eat and go to the bathroom and then go back to sleep.
Nicole's mother, Vicki, said her daughter will sleep 18 to 19 hours a day, and when she finally wakes up to eat she is in a "state of sleepwalking which she does not remember."
Delien’s family also appeared on a syndicated talk show this week to ensure that other families are aware of the rare disease.
Vicki Delien told reporters it was very frustrating trying to get a diagnosis for her daughter. She said it took several trips to a hospital to find out what has been affecting her daughter.
Finally, a doctor at Allegheny General Hospital in Pittsburgh, Pennsylvania, was able to identify the disorder and offer some suggestions on how to manage the disease, including medication.
"Affected people may go a period of weeks, months or even years without experiencing any symptoms, and then it reappears with little warning.
