Okay, so I've been doing a lot of research on trauma-induced comas, and am quite curious as to whether or not it is possible to dream whilst in a coma. I've gathered that medical-induced comatose, using chemicals/anesthetics, causes more of just a jet-lag effect, and you don't have any dreams.  Considering those aren't natural comas, I wouldn't assume they would result in dreaming.
 Trauma-induced comas, however, I have researched can result in dreaming, although many people deny it. I read an interview about a girl who was a comatose patient after being in a car accident. She dreamed she was a mouse, and was trying to get to the top of a staircase, however there were crows that weren't allowing her near the top. Perhaps the top of the staircase was her way out of the coma. Well anyway, she said she was aware of what was going on outside her coma, in the physical world. She heard the doctors talking about other patients, and operations and thought that they were opperating on her.
 I read a few other things on trauma-induced comatose and dreaming. Many people deny the possibility of dreaming during a coma, for the fact that brain waves wouldn't be as active. So I researched brain waves, and mostly just got hits on lucid dreaming. Not much on brain waves versus comas.
So I was wondering if anyone has ever been in a coma, or know somebody who has, and if they dreamed whle in the coma, or remember anything. If so, could you tell me?
Thankyou!
