This is the most commonly reported experience of someone who almost dies. Moments of their life flood their brain in slow motion, meaningfulness is implied.
Clearly something triggers it, something perhaps biochemical. Which means we might be able to trigger it!
It could be like a DMT trip – life changing.
Couple it with advances in recording thoughts (the science has begun) and we could have a very interesting product. What does your subconscious care for the most in its last moments?
