I’m currently reading Einstein’s Dreams, by Alan Lightman.  It’s a book which hypothesizes about what might have gone on in the nocturnal subconscious mind of Albert while he was formulating his theories on time.  It’s a dream log of sorts.  I used to keep a dream long.  In fact, in high school I got to the point that I was able to remember four dreams every night.  Of course nothing in the book is true, but so far, it’s very fascinating.
