Amazing story Gimpy. A few similarities to the OP story.
Can I ask a few questions ?
How vivid and detailed were the recalled 'memories' ?
Extremely vivid. I could smell the merangue shells.
]Did time seem to slow down ?
I had no sense of time whatsoever. Remember that I am in full panic mode. I can only imagine what hormones and chemicals are racing through my system right at that moment. Flight-or-fight instincts on red alert.
Was there any assessment of your life events going on or just viewing ?
Just flashing by, like a mish mosh of images and sensations, no editorializing, no "assessing."
Did you recall anything that you had otherwise forgotten ?
Well, in the merangue image, I was around 3 years old, and the shells were on the counter cooling off, and I was hiding below the counter and when my mom turned around I reached my hand up to steal one off the counter. I had no working memory of that event until it "flashed." But I was able to tell my mother what she was wearing, what color the laminate flooring was and other details. She did remember the incident.
Was it life changing in any significant way (other than 'got to do something about that stupid car') ?
Absolutely none. I can't imagine why there would be. It was an organic experience, not a supernatural one.
I thought I was going to die in a matter of seconds, and was desperately trying to keep that from happening, though I felt trapped and helpless.
My "life" flashed before my eyes, seemingly all at once. That was about 25 years ago, so over time I have forgotten some of the vignettes that appeared, but I have not forgotten that so many did. Even the bad ones. There were flashes of several of my most tragic encounters. Again, it was not with any editorializing, it was just all there.
As soon as my car jerked forward, I realized how fast and hard my heart was pounding and how fast and deeply I was breathing and I was shaking uncontrollably for quite a while. And I believe I was crying as well.
If I recall, I had a headache not long after that. Again, likely due to the sudden influx of hormones and chemicals, and the sudden drop. Who knows?
