from The Dragons of Eden, by Carl Sagan

We can now recognize the very attractive possibility that the left hemisphere of the neo-cortex is suppressed in the dream state, while the right hemisphere--which has an extensive familiarity with signs but only a halting verbal literacy--is functioning well. It may be that the left hemisphere is not entirely turned off at night but instead is performing tasks that make it inaccessible to consciousness: it is busily engaged in data dumping from the short-term memory buffer, determining what should survive into long-term storage.
