I can honestly say, from first hand experience, that my life didn't flash before my eyes when I thought I was going to die. My exact thoughts were:
There were no pictures. Just those words. In the dark. In the middle of the night.
I have no idea what happened. I was sleeping and dreaming when, in my dream, I realized I couldn't breathe. I woke up immediately and realized I really couldn't breathe. It took maybe five or six seconds for those thoughts to flash through my brain. Thankfully, the coughing dislodged whatever it was that was stopping me from catching my breath. By the time I got to "Die." I was already out of bed on my way to my son's room for help. Up until the second "NO!" there was panic and intense fear. At that point I got very calm. And coughed. And saved myself. And coughed some more.
So any way, I'm still here.
