For example under normal circumstances, I would've noticed the scooter etc. The accident happened in a fraction of second. But my brain already thought of all the possible ways it could end and also it took a 'picture' of that moment. Like it was hyper aware or something
Have you been in a situation where your brain processes every single information at that moment?
I've been in a bicycle accident when I was 9th grade and I remember the model of the scooter that hit me and what happened exactly.
My friend was in an car accident where he had a similar experience
