One thing to consider is the existence of what SF calls "bullet time", or when time appears to slow.
This is what it feels like when, in addition to your heart racing, you literally are recording everything you perceive. We get rid of almost everything we see, hear, feel, touch, and taste, but in bullet time, or emergency time, we turn the recorders on full, so that we can analyze how we escaped the dingoes trying to eat us, or the event that might have killed us.
If we did that all the time, we'd run out of storage. So we toss most of it away.
On a personal level, it is kind of cool. But it's there for a reason, to help you learn to avoid things that might get you killed, or almost did.
