I don't know about gelling, I've never had anything profound enough to amaze me in PR.
But, after PRing on some occasion, I leave with the impression that all the info is swimming in my mind somewhere, and its interesting. I can "feel" the contents in my mind. My friend, who I introduced PR to, could testify on this too. If I could get my mind still enough, I'd probably be able to retrieve the stuff.
