Interesting. I am one to dream every night - very vivid, technicolor dreams, and sometimes I remember more than 1. I have, several times, in the past felt consciously that my brain was 'filing things' while I was asleep, and dreaming.

It isn't any alphabetical filing though, lol. I've been aware that sometimes I seem to file things in related triads. IE Recently I was aware that memories of Dr. Joycelyn Elders, Dr. Evelyn Pagilini and Dr. Joyce Brothers all seemed to be sharing the same neuronal access point.
