The right brain is looking for and trying to fit the strange pieces that it encountered
during the day into a recognizable pattern. The left brain’s projector,
your working memory, is off. Then across the corpus callosum
come the languages of the right brain – the languages of symbol,
ritual, metaphor, simile, color, and associative memory. All of
these things tumble across the divide and appear on the now
empty visual, spatial sketch pad of the left hemisphere of the
brain. We call this dreaming.
