Carolina Olsson

Karolina Olsson (29 October 1861 – 5 April 1950), also known as "Soverskan på Oknö" ("The Sleeper of Oknö"), was a Swedish woman who purportedly remained in hibernation between 1876 and 1908 (32 years). This is believed to be the longest time that anyone has lived in this manner who then awoke without any residual symptoms.
