A 32-year-old mother from Manchester has recalled waking up believing she was a schoolgirl following a sudden bout of amnesia.
In 2008, Naomi Jacobs went to sleep and arose thinking that she was a 15-year-old in the middle of her GCSEs, which she took in 1992.
She was later diagnosed with transient global amnesia - a form of acute memory loss brought on by stress.
At the time, she was studying for a psychology degree and running her own homeopathy business while continuing to care for her 11-year-old son Leo.
"I fell asleep as a bold, brassy, know-it-all 15-year-old - and woke up a 32-year-old single mum living in a council house," she told The Sun.
Jacobs further confessed to screaming when Leo addressed her as "mum" on that fateful morning.
"I began sobbing uncontrollably. To say I was petrified was an understatement. I just wanted my mum. I couldn't get my head around going to bed one night and waking up in a different century," she explained.
On her continued attempts to adapt to the 21st Century, she added: "At 15, I thought I would have conquered half the planet by the time I was 32. It was a massive shock to discover I was just an ordinary single mum driving a battered old Fiat.
"For the first few months, I was desperately trying to make sense of who I was. At night I'd lie awake and cry, longing to be back at school, when all I had to worry about was the boys I had crushes on and getting caught drinking in the park. But slowly I started to get used to the world again."
