Out of Body For Weeks After Near Death Experience

This woman died from injuries she sustained in a car accident at the age of 17. Nothing special here. Except that she frequently traveled out of her body after her near-death experience. And although she was severely injured and required physical therapy and rehabilitation—he was also unaware of these injuries. At the time, she believed her physical body was fine. This makes me wonder, do others who are this severely injured, have the same type of awareness? How can a person appear comatose and yet be fully aware of their surroundings and even travel out of their body while in a coma? Should this reality change the way in which we interact with people who appear to be unresponsive?
