People who know about NDE and how adrenaline works in the body..?

I took a college course in Near Death Experiences. What you experienced was not an NDE. It is a prime example of adrenaline rush and overload. It creates a flight or fight reaction common in a situation like yours. Numerous people do things to get that feeling , bungee jumping, driving like a maniac, etc. Unfortunately, sometimes they misjudge their stunts and die trying.

It's common for people to associate the adrenalin rush with this sort of experience, because many do have your experience of altered time while experiencing physical danger that releases the flight or fight response. It's very shocking and memorable. But I'm not certain adrenalin is necessary to have a change in the perception of time. Some seem to have it when they're "in the zone." Shamans use psychedelics to instigate this change in awareness. If there were a verifiable physiological cause for this, then I think it would be already be widely known, and it just isn't. It's one of those mysteries yet to be discovered that we can be thankful for. Experiments to test a connection between risk or danger and the perception of time wouldn't be considered ethical, and it's very unlikely that people in everyday situations experiencing danger could be monitored for their perceptions and physiological response. Usually there's a series of flashbacks of one's life that's commonly reported in life-threatening situations, but you did not report these, and this anyway might not be what's thought of as NDE, where one has the perception of leaving ones body and doctors have verified the loss of vitals. I'd suggest that you keep your experience in mind, and stay observant of any future changes that might not be so dramatic as this one was. Then you might get a better sense for what it was.
