Dreaming in Bytes
The brain is like a sponge, absorbing experiences during the day that may be acted on immediately and stored for later. Knowledge is constructed by integrating this new information into a semi-permanent file. When we weigh it up against what we already know and find it compatible, we accept it as truth. There is a critical factor in this judgment, which is skepticism. If something doesn't seem quite right to us, these unresolved experiences often come out in dreams. Our brains have filed these preoccupations into folders where they can be accessed and put forward for resolution at a later date. When an unsettling replay resists classification, the process of dreaming tries to re-enact a scene to understand what occurred, matching it with similar settings, characters, and emotions. If the unresolved event is eventually understood, it can pass into our knowledge base as an evidential cohesive fact. If it is not resolved, it is put back into storage so it can be returned to the luggage carousel at a future date and mixed with a different set of suitcases to see if it now makes sense.
Some cultures believe that dreams are an alternate reality, and this, to me, is akin to the theory of a parallel universe – neither proved nor disproved. Some believe that knowledge is passed on in dreams, and to some extent, this is true, but waking reality plays a larger part in our understanding of the world. Since empirical knowledge is stored in an area that is accessible in dreaming, the mixed salad of our dreams also contributes to our knowledge base. When some undigested experience resurfaces in dreams, it can play out in a way that helps us understand it better. It isn't often that dreams are understood immediately, but the practice of writing them down can reveal their truth long after the fact, even if it is only to reinforce our emotional state at the time we dreamed them. Often, we don't recognize this state until it has passed and been filed in our memory. The way experiences are processed may have a territorial factor that harks back to the disgraced belief in phrenology, but has now returned thanks to the technology of CAT scans and MRIs. When someone says something is “in the back of my mind”, common experience tells us that the brain cells used for storing more permanent knowledge are located deep in the cranial filing cabinet. Frontal brain cells, among other things, control our more immediate facial and lingual responses. When a person says something is “on the tip of my tongue,” it is an indication that the frontal engine is trying to access the dustier reaches of our minds before it can move the information forward.
Filing cabinets of memory can work like a zip file, remaining compressed, occupying little space until a trigger or command asks for an unzip and the file or memory expands. Often, this trigger occurs in dreaming. Memory access during a dream isn’t a perfect search, but all of our memory searches in waking time aren’t always successful. When we are awake, an unexpected memory or desire can drift forward at an inappropriate moment. Unrelated events, scenes, and people can populate dreams, sometimes causing perplexing combinations. Often, we wake from dreams asking ourselves, “What was that about?” Unless we can separate extraneous elements from relevant ones, we can’t make sense of our dreams.
Sometimes a dream - more often a nightmare - will wake us. Before we wake, our body will try to react to an event in the dream, and we will kick, move our arms, try to speak, grunt, or shout aloud. Sometimes we enter a half-waking limbo, where we know we are dreaming, wish to wake up but can’t, and consciously try to move or make a noise that will wake us. Informed by the body's need, our knowledge base tells us that we are dreaming as the body struggles to overcome sleep paralysis. Our survival instinct knows that remaining in a panic state for a long time will be traumatic to the brain, and therefore signals the brain to push us up into consciousness. This struggle can also be thought of as the workings of the frontal brain and the rear brain to communicate. It is now widely accepted that the brain stem at the back of the brain controls the motor functions like breathing, heartbeat, etc., and the survival instinct is based there. Since messages travel across protein networks, it takes time to assemble the appropriate files to travel the circuits from the back to the middle knowledge base to the frontal cortex. It can take a few seconds to wake up from a nightmare. We are, after all, humans, not high RAM computers.
Generally, our brain tries to do what is best for our body. The body is the vessel for the brain. Included in this instinctual health program are dreams. Our mind tries to digest our experiences in an automatic defrag, which takes place every night. Defrag is short for defragmentation, which attempts to re-file stray bits of information so there are more blocks of stable usable space available for new memories. Unless we defragment our brains for a period every 24 hours, we do not remain effective, rational, or sane in our waking lives.
There are computer programs that suggest the user should delete information that is not connected to any usable material or that has not been accessed for a long time. Much like a computer, our brains sometimes tell us that certain bytes of information are gone, permanently deleted, but this is not actually the case. Microsoft and other computer systems would have us believe that deleted information is unrecoverable, but those who understand computers on more than a superficial level know that everything which was once there is still there. This is also true for the brain. We don’t really forget, we only can’t remember. Sometimes what we thought we had forgotten will return to us at unexpected moments. Sometimes lost memories return in dreams.
Dreams are natural, useful, healthy, elusive things. We benefit by understanding them. The antidote to fear is self-knowledge. The antidote to communal fear lies in understanding our world. Dreams help all of us in all realms.
