15-Year-Old Girl Mysteriously "Hibernates," Sleeps for 19 Hours and Unresponsive to Cold Water

Xiaohong (not her real name), a third-year junior high school girl at the Yellow Crane Tower School in Wuchang, has suffered from excessive daytime sleepiness since two years ago. She usually goes to bed at 11 p.m., but normally does not wake up until the afternoon the next day. Neither her family nor teachers are able to wake her up, no matter what methods they try. Yesterday, the vice principle of the school, Ms. Lai Congrong, called our newspaper for help.
