Naomi Jacobs, 34, woke up in 2008 but believed she was just about to sit her GCSE exams in the summer of 1992.
The last thing she could remember was falling asleep in her bunk bed as a schoolgirl. She was horrified to learn she was living in the 21st century, and was even mother to an 11-year-old boy she did not recognise.
Doctors revealed that Naomi had been under so much stress that part of her brain had simply closed down, erasing many memories of her life.
She was left baffled by the internet, and flummoxed by her mobile phone as she struggled to get to grips with modern life.
Today, three years after waking up in the future, Naomi has finally regained most of her memory, and has written a book about her experiences.
She said: "I fell asleep in 1992 as a bold, brassy, very confident know-it-all 15-year-old, and woke up a 32-year-old single mum living in a council house.
"The last thing I remember was falling asleep in my lower bunk bed, dreaming about a boy in my class.
"When I woke up, I looked in the mirror and had the fright of my life when I saw an old woman with wrinkles staring back at me.
"Then this little boy appeared and started calling me mum. That's when I started to scream.
"I didn't know who he was. I didn't think he was much younger than I was, and I certainly didn't remember giving birth to him.
"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."
Naomi, who was a psychology student before her memory loss, was told by doctors that she was suffering from Transient Global Amnesia, a form of memory loss brought on by stress.
The "episodic" part of her memory had completely shut down meaning she had lost all her emotional memories.
However, her semantic memory was still intact so she was able to remember things she had repeated over time such as how to drive.
Slowly she began the difficult task of piecing her life back together by ploughing through years of her diaries and journals.
Naomi 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, living in Manchester and driving a battered old Fiat Brava.
"At first, I struggled to leave my home, and venture out into the world - but slowly, with the help of my family, I started to get used to the world again.
"Although it was traumatic, I'm really grateful for being thrown forward through time now.
"I've been able to follow my childhood dream of becoming a writer - and am currently writing my story."
It is possible that this woman was under a serious stress, and her subconscious remembered times when she felt much more confident and in control. And so, as a safety mechanism, she was switched to this part of a 15 years old.
