Answer 1

First, adrenaline during the event makes you react faster, so you can actually percieve it all and not just miss most of the event. Second, what you remember is not always what happens. Such an event will be a very bright detailed memory, so in retrospect you percieve it as longer lasting, you just remember more of it than other events.
