T-Rex: People talk about how when you die, your life flashes before your eyes!

T-Rex: But that takes time to experience, yes?

T-Rex: Otherwise, logically, it would be going WAY too fast to discern anything, least of all that it's your ENTIRE LIFE. And so, given the premise of the idiom, we can conclude that this life summary is not LITERALLY happening in a flash, but MUST be happening slower!
Dromiceiomimus: Slow enough, perhaps, to see and understand it?

Utahraptor: Slow enough, perhaps, that it could be perceived as happening in REAL TIME??

T-Rex: OH SNAP! You're suggesting that what we THINK is reality could actually be a REPLAY of our entire lives flashing before our lives just before we die? WHAT A TWIST!
Utahraptor: Not really, since it still amounts to you experiencing being alive for a bit and then dying.

Off panel: That's the story of ALL our lives, bud.
T-Rex: Hah hah hah!
T-Rex: It is WAY too early in the morning for this!!
