Partly of this is not just the profusion. It's the placing. The point of view character needs to focus on what the point of view character would focus on.

Pondering life, the universe, and everything gives you more time to note details, if you're the sort of person that notes details.
To be sure, I have heard that adrenaline can make everything more vivid. And shock can produce some odd reactions. However, that's one thing I'm sure never to research.
