Short subject or feature length?

One of my first posts was a quote from Lawrence Block's Everybody Dies:

"When you die, it is said you see your whole life. But you don't see it minute by minute, like a speeded-up film. It's like everything you ever did in all your days was a brushstroke, and now you see the whole painting all at once."

Poet Billy Collins has a different view:

I wonder how it all got started, this business
about seeing your life flash before your eyes
while you drown, as if panic, or the act of submergence,
could startle time into such compression, crushing
decades in the vice of your desperate, final seconds.
From The Art of Drowning
