(FOXNEWS) — Michelle Myers is a woman from Arizona who’s never left the country. But although Myers used to speak like any other American, the 45-year-old now talks with a British accent, reports the magazine Smithsonian.

Her accent literally changed overnight when Myers went to sleep with a headache and then woke up with a British inflection. Though it might seem comical, her rare language change is actually a medical condition called Foreign Accent Syndrome (FAS).
