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.
