Lily Clarke, 21, can sleep for two months at a stretch, suffering from a rare medical condition called Kleine-Levin Syndrome.
Her 18th birthday went by without a party as she fell asleep just a few days before her birthday. She slept through University exams, Christmas and New Year.
Clarke came down with this condition in 2007. According to Adele, Lily Clarke's mother, she sleeps for 2 months at a stretch every seven months.
Unfortunately, there is no available cure for this syndrome which mostly affects young people.
