It's possible, but completely anecdotally I was in a six car pileup and watched the stuff move from my backseat to the window to smash against it in what felt like 20-30 seconds.
I remember clearly having several thoughts in what could not have been more than 1 second between getting hit and my entire car smashing into another at 60 mph.
"Oh, that's my kleenex box, dang that's just hanging there huh?"
"What's that noise? Oh, its me screaming."
"I better hold my self against the steering wheel for the airbag... wait, if I am thinking this that means there's no airbag"
I remember watching my seatbelt break and snap across my chest, moving like a languid snake, barely motivated to snap back to the wall.
However, many other times in my life in extreme situations nothing like that happened, so I don't know if just jumping off a cliff is enough trauma or fear of death to cause it reliably.
