Not being able to sleep is a common problem for many people, but Li Zhanging has taken it to a whole other level.
She claims her sleeping issue started when she was just five years old…and she hasn’t slept since...that’s forty years.
She’s gone to doctors, who are “baffled” by the fact that her nervous system appeared “normal” even though she’s gone sleepless all that time.
During a more extensive sleep study, they found that after 16 hours her monitor showed her in “light-to-moderate sleep,” but when they checked on her, she was talking to her husband. That led experts to conclude that she was able to “sleep while awake,” which is something similar to sleep walking.
