Not sure if this has anything to do with the topic.
I once had an experience while crashing a car.
It was told to me by witnesses that I rolled 5 times,not endo but side to side roll.
So when rolling I had a connection with a single blade of grass.
I seen it as my roof of the car was upside down and rolling so the blade of grass was at the top of my windshield along with the rest of the grass in the ground.
The funny thing was it was like I wasn't aware of the flipping car only the blade of grass and I was concerned for it. After pondering it years later I figured out my consciousness or awareness was 180 degrees or upside down from my body.
So I figure it was similar to some type of out of body experience.
There was no fear while rolling and all that was important was that blade of grass.I remember and can still see it to this day clear as a bell.
I must have popped out briefly for some kind of protection or something.
