One morning in 2008, 32-year-old Naomi Jacobs woke up in a home she didn’t recognize, to a son she didn’t know, thinking she was 15 years old. Jacobs, who is British, wasn’t admitted to a hospital the night prior for any head trauma. Rather, her personal memories disappeared due to a rare form of amnesia called dissociative amnesia, which is induced by stress, BBC reported.
“Initially I don’t recognize the room, the bedroom that I’ve woken up in, the bed that I’ve woken up in. I jumped out of the bed in shock,” Jacobs told the BBC.
