An incredible condition that sees a Chinese man sleep for six months of the year and stay awake for the rest of it has puzzled doctors.
Li Zhiming's family has to look after the 74-year-old throughout the entire time he's asleep.
They said that they have to make him sit and feed him warm soup.
They also have to make him wear a NAPPY because he doesn't even wake up to go to the bathroom.
"When he is sleeping it is like he is in a coma," the Sun quoted Fu Yip, his daughter-in-law, as saying.
"We can't rouse him at all - if we put spoonfuls of soup in his mouth he swallows automatically but otherwise there's no response.
"Then when he wakes up he doesn't sleep for six months - wandering around the streets at night to amuse himself or watching television," she added.
