Dream Time

DreamingLike most people, I seldom remember my dreams. When I do, or when only the powerful feeling remains, I know that they are very emotional events. Something is always going on, and my attention is riveted. I recently read J. Allan Hobson’s Dreaming: An Introduction to the Science of Sleep. It must be intimidating, I have to note right away, for a neuroscientist to write a book. Our understanding is changing so rapidly that even academic treatments become a kind of ephemera. Published over a decade ago, it shows its age. Even I’m aware that changes in brain science have occurred and perceptions have changed somewhat since then. What struck me most, however, is Hobson’s absolute confidence that mind is a function of the brain, and that dreams are merely the madness we experience when we sleep. The madness I don’t mind so much. The materialism, however, I think is largely wrong.

Consciousness remains a great unknown. There is disagreement around whether it is emergent—coming from the brain, or receptive—perceived by the brain. Or perhaps something completely different. One of the greatest human foibles is to claim that we understand anything completely. I’ve always been amazed—knowing that the world involves much more than just sight, sound, scent, taste, and touch—that some scientists are so quick to write off complex experience as “merely” activity in the brain. Some animals, for example, seem to perceive magnetic fields. Others use navigation devices we simply don’t comprehend. They may experience senses we don’t even have. And yet, we happily claim that we’ve gotten this one nailed down. Dreams are only activities in the brain when we sleep.

Only? How can any dreamer say that this is only chemical reaction in our heads? The experience of dreaming is, implicitly, so much more than just random thoughts. Hobson does a good job describing how dreams are a form of madness, a psychosis when the reasoning part of our brains are inhibited. Fair enough, but who can experience madness and think it completely material? Our minds are more complex, it seems to me, than we give them credit for being. Hobson begins the book by noting that dreams used to be within the purview of religion. Since has now claimed them. We have an entire universe in our skulls, and yet we insist that although we don’t understand it, we can be certain that it is nothing but material. My dreams continue to suggest a different reality.
