It is amazing how fleeting the memory of a dream is. It's also funny when you wake up with absolutely no memory of a dream, and something later in the day makes you suddenly remember the dream.

This happened once years ago when a colleague asked me where I wanted to go for lunch. I said, "How about Dewey's?"

He looked at me with a puzzled look that confused me because we had gone there about once a week for months. I eventually realized that the place had had a new name for years and the previous night I dreamt that it was still "Dewey's." If you had asked me the day before what the name of the place used to be, I would never have been able to tell you. Somehow it came back to me in a dream that left my memory in the morning.
