How do dreams occur?
Sleeping is a form of Relaxing after a long day of work. Sleeping is an action where we spiritually disengage from our body to relax and our souls wander around. This process is when dreams happen. Dreams are thoughts, images, and sensations occurring in a person's mind during sleep. However, when our brain is unwinding and relaxing after a long day? How do we get our dreams?
REM sleep is when dreams most frequently occur," says Benge. "Our brains actually show activity very similar to wakefulness if we looked at REM sleep on an electroencephalogram, a test used to detect electrical activity in the brain." While some research indicates that those in the slow wave sleep cycle may dream—with these being pieces of more coherent memories—most people who wake up from REM sleep report having their most vivid or bizarre dreams. "During the day, our brain processes sensory inputs and synthesizes them to form our experiences. We don't actually 'see' or 'hear' anything," said Jared Benge, PhD, ABPP-CN, a neuropsychologist with Baylor Scott & White Health in Temple and assistant professor at Texas A&M College of Medicine. "Even though we are not receiving sensory inputs during a dream, the brain regions responsible for these functions are still functioning, allowing our experiences to seem genuine."
It is no wonder that the most interesting and unknown part of human consciousness remains dreams—colorful, often weird experiences happening when you are sleeping. These bouts of mental, emotional, and sensory experiences occur most significantly in relation to sleep during the REM state of sleep, characterized by increased brain activity. REM is the time when dreams become very vivid, full of fantasies, highly emotionally charged, yet including elements from a person's everyday life in distorted forms. The purpose of dreams has formed the basis for a lot of debate and research. A strong theory is that dreams are important for processing memories, meaning the mind organizes and strengthens the information gathered daily. It may be a replay of current events in a distorted way so that your brain can understand and store relevant information. Another influential theory is that of the emotional regulation theory, where dreams play a role in managing emotions.
The idea here is that, through engaging and re-rehearsing feelings in illusory situations, the brain makes use of the medium of dreams to regulate feelings. Very well, especially those associated with stress or anxiety, which links back again to mental housekeeping. This sub-theory puts forward the idea that dreams help "clean up" the mind by erasing information considered irrelevant or erroneous. Some scholars believe that there is no meaning to our dreams and that they simply represent the random activity of our brains when we are asleep. Despite these theories, researchers have not been able to define the purpose of having dreams, and interpreting a dream is highly subjective. Non-REM dreams typically consist of more factual thoughts or memories rooted in reality, while REM dreams are usually much more surreal and bizarre. One side of the continuing argument about the intrinsic significance of dreams is the "continuity hypothesis," which holds that dreams and waking life are entwined and share overlapping themes and substance. Another camp is the "discontinuity hypothesis", which holds that dreaming is a different cognitive process from our conscious thinking. Though still in its formative stages, the science behind dreaming does make it pretty evident that these nocturnal experiences are very important for knowledge about the human mind and consciousness. Indeed, dreams create this amazing window into the intricacies of our inner world, whether they are seen as a reflection of waking experiences, as a means to process feelings and memories, or simply as an outcome of the complex processes the brain goes through.
Every night, we go to bed and fall asleep. Only then does our mind embark on mysterious journeys that are interwoven into the weavings of our daily lives.
In so doing, studying dreams serves not only to further deepen our understanding of how the human brain works but also allows us a view of the infinite imagination and unpredictability characterizing the human experience. Whether through vivid narratives that engage us or abstract images that puzzle us, dreams remain part of the mystery of being human. Every night, as we drift off to sleep, our imaginations take us on enigmatic excursions; these are part of what forms the fabric of our everyday lives. It helps us to understand more of how the brain works and serves as a constant reminder of the unpredictability and limitless creativeness that is part of being human. Dreams, whether they give vivid stories that enthrall us or abstract pictures that confound us, continue to be a crucial component of the mystique of the human condition.
