What’s the physiological difference between being unconscious, and just being asleep?
In: Biology
If you fall asleep and someone wakes you hours later your brain is aware if the passage of time and you are groggy but aware that you just woke up.
Personal experience here. I went in for surgery and the doctor put me under. I awoke in the recovery room hearing my wife talk to someone. I clearly remember wondering what my wife was doing in the operating room. During this the brain itself is unaware of events and the passage if time.
