In 2008, British woman Naomi Jacobs went to bed one night, she was a 32-year-old mother. When she woke the following morning, her world had changed. She didn't recognise her home, nor her 10-year-old son. She had a new persona, believing she was a teenage schoolgirl living in 1992. The diagnosis was dissociative amnesia. And so began her journey to piece her life back together. She has written a book about her astounding experience, called I Woke Up in the Future, published by Macmillan.
