I wonder if the memory carousel itself is not so much a survival mechanism, but rather it's a side effect of a survival mechanism. In layman terms, the brain goes into overdrive as it tries everything it can to eek out some minor optimization in your movement, that might help you dodge an arrow. As a side effect everything else in your brain also gets stimulated like never before and for the parts of your brain that we relate to consciousness, the experience is one of explosive recall of memories.

Wow, I like your theory. Would be really cool if it’s that way. Like when you have tunnel vision during a fight and your hands get numb
