LONDON: A teenaged British girl, who missed her exams and even celebrating her birthday after nodding off in April, woke up last week.
Stacey Comerford, 15, from Telford in the West Midlands region, suffers from a rare neurological disorder which means she enters a sleeping state for months at a time, The Sun reported.
She is just one of 1,000 people worldwide to be suffering from Kleine Levin Syndrome also known as Sleeping Beauty Syndrome.
The last - her longest at two months - meant she missed nine exams after being predicted straight As.
Stacey, who hopes to return to school part time, said she used to be taunted over the condition.
She said: "I've missed nine exams and my birthday. It's easier now people know what it is. It's easier to explain to them. Before, people didn't believe me. That was the hardest thing."
