A guy is able to repeat back words that a doctor said to another doctor, while this patient had no brain activity. That's simple or you are simple?
What guy? When and where was this? Was there brain monitoring equipment hooked up to "the guy" that showed that there was
no brain activity, and at the same time a recording of the activities and conversation in the operating room that shows that the doctors spoke those words at the exact same moments that there was no brain activity?
I think you are making this all up. If there is no brain activity then you are dead....forever. If a patient flat-lines, that means their heart and respiration have stopped, but the brain does not immediately stop functioning also. That is why it is critical to get oxygenated blood flowing to the brain within a few minutes or permanent brain damage occurs, but if brain activity stops you are dead.
If anesthesia is not deep enough patients may be aware of some of the activities around them and may remember it later.
I would be a lot more inclined to believe you if you told us
who, when and where.
Enjoy.
