Dreams and Sleep

Dreams have been a mystery throughout human history, leading to various interpretations and speculations. Dream analysis has traditionally been the domain of psychoanalysts and fortune tellers. This article explores the mechanisms of sleep and dreams from the perspectives of philosophy, physiology, psychology, and neuroscience, aiming to provide new insights into understanding oneself and unlocking potential.

Slow Wave and Fast Wave Sleep

Research on brain waves (EEG) reveals that we dream during every sleep cycle. Sleep consists of two types: slow wave sleep (SWS) and fast wave sleep (REM). Initially, we enter SWS, followed by the first REM period after about 90 minutes. These cycles alternate throughout the night, with approximately three to five cycles occurring. The first REM period lasts about five minutes, gradually increasing in duration in subsequent cycles.

During REM sleep, a phenomenon called Rapid Eye Movement occurs. If woken during this phase, a person can recall their dreams; however, waking them five minutes later often results in forgetfulness. Studies worldwide confirm that dreaming predominantly occurs during REM sleep, which is thus referred to as the "dreaming period."

Neuroscientific and Psychoanalytic Interpretations of Dreams

Interpretations of dreams have sparked widespread interest and debate, generally falling into two camps: neuroscientific and psychoanalytic.

1. Neuroscientific Perspective: F. Crick posits that dreaming serves to organize memories. He suggests that dreams are not reminders but rather a mechanism for forgetting unnecessary information during REM sleep, preventing cognitive overload. The brain's activity generates images, and the forebrain attempts to construct dreams from these signals. Thus, seeking meaning in dreams may be futile.

2. Psychoanalytic Perspective: S. Freud argues that suppressed desires and thoughts surface in dreams, albeit disguised. Analyzing dreams can reveal underlying issues and repressed emotions.

New Theories on Dreams from Computer Science

Is REM sleep synonymous with dreaming? Research indicates a 70% chance of dreaming during this phase. However, fetuses and newborns experience REM sleep up to 100%, despite having minimal life experiences. This raises questions about their need for extensive dreaming.

Both Crick’s and Freud’s theories fall short of satisfactory explanations. Scholars T. Newman and C. Evans suggest viewing the brain's dreaming process through a computer science lens. They liken the brain's inability to perceive external stimuli during sleep to a computer pausing operations to input or modify programs, suggesting that REM sleep may facilitate this process.

This innovative theory effectively explains the extensive REM sleep required by fetuses and newborns, as their brains are busy encoding essential survival programs. This computer programming analogy not only bridges the gap between Freud and Crick's theories but also advances our understanding of various brain mysteries.

Exploring Dream Phenomena

Dreaming is a normal physiological and psychological process, essential for mental well-being. Just as sleep restores physical energy, dreams play a crucial role in emotional regulation. Without dreams, many individuals might develop psychological disorders. Freud suggested that dreaming is a form of "neurosis," while those with mental health issues are merely living out their "waking dreams."

Analyzing dreams reveals several categories:

1. Physical Stimuli During Sleep: External factors like temperature can influence dreams. For example, feeling cold may lead to dreams of icy landscapes, while thirst may manifest as searching for water.

2. Residual Daytime Activities: The saying "what you think about during the day, you dream about at night" holds true. Many scientists have reported breakthroughs occurring within their dreams.
