Mind-Reading Scanner Could Record and Analyze Dreams, Says Brain Researcher | Popular Science: "Cerf believes that it’s possible to create a system that would allow psychologists to compare patients’ recollections of their dreams with an electronic visualization of the activity in their brains, and he’s taken the first steps toward doing so via a study that associates specific, individual neurons with specific objects or ideas.

By building a database of associations for each patient, Cerf and his colleagues could figure out what a patients was thinking about without him or her saying so. With a large enough database, the thinking goes, a third party could “read minds” by looking at which neurons light up during the course of a dream, creating an electronic record of said dream."
