Emotional selection is a psychological theory of dreaming that describes non-REM dreams as modifying mental schemas and REM dreams as testing prior non-REM modifications. [1] [2] The schemas modified and tested by emotional selection are those essential for meeting human needs, such as those defined by Abraham Maslow and Henry Murray. For instance, a dream of being attacked, chased, or falling would test schemas' ability to cope with situations when the need for safety is thwarted; a dream of being rejected by a loved one or a group would test the dreamer's ability to accept situations when their belongingness needs are unmet; a dream of failing an exam, accidental nudity, or technical difficulties would test schemas' ability to cope with an unmet need for esteem; and so forth.
As an example of emotional selection in action, a dreamer's sense of independence may be elevated by processing a non-REM dream in which he or she acts independently, such as competently completing a complex task or successfully navigating a challenging social situation. During this non-REM dream, schemas accommodate the dream's theme, resulting in an elevated sense of independence at the close of the non-REM sleep phase. Despite the goal of enhancing schemas, such accommodations can be unintentionally maladaptive. For instance, children typically benefit from a blend of dependence and independence, as an overly developed sense of independence can result in them wandering into dangerous situations. Due to such potential maladaptations, during subsequent REM sleep, a second set of dreams is executed in the form of test scenarios that test the prior non-REM accommodations. In our example, the dreamer may find themselves exercising their newfound elevated independence during a REM dream of exploring a dangerous environment or singlehandedly coping with a complex problem. Regardless of the dream scenario, during a REM dream, the mind monitors its emotional response. If the prior accommodations alleviate anxiety, frustration, sadness, or in other ways appear emotionally adaptive during the REM dream test, the accommodations are selected for retention. Those accommodations that exacerbate the emotional response are abandoned or further modified and tested.
Emotional selection's descriptions of REM dreams as tests explain why dreams are often bizarre. Common dream scenarios that incorporate outwardly bizarre scenarios, such as teeth falling out, accidental nudity in public, monsters, flying, and other surreal objects, characters, and situations, provide the extreme conditions necessary to test whether mental schemas can cope with trauma and other severities while awake.
Emotional selection also explains why dreams can be both pleasant and unpleasant. As summarized in Emotional Selection: How Your Dreams Evolve Your Mind:
...after the accommodation phase, the dream process moves to the emotional selection phase, in which dreams serve as test scenarios that tax prior tentative accommodations. These dream tests can be unpleasant, including themes of being chased, falling, being rejected, and performing poorly. Such unpleasant themes test schema modifications that cope with thwarted needs. Conversely, emotional selection also processes dream tests with pleasant themes, such as flying, finding treasure, making discoveries, and achieving success. These enjoyable themes ensure schemas can embrace occasions when our needs are satisfied. [3]
Emotional selection theory is akin to natural selection. Charles Darwin described evolution as a process that includes two phases: a modification phase (variation) and a selection phase (natural selection). Emotional selection also includes two phases: a modification phase (accommodation) which occurs during the neural plasticity of non-REM sleep, and a selection phase (emotional selection) which occurs during the high neural activity of REM sleep. However, unlike the life-or-death tests described by natural selection, emotional selection theory employs dreams to evolve mental schemas during sleep.
In the psychology subfield of oneirology, a lucid dream is a type of dream wherein the dreamer realizes that they are dreaming during their dream. The capacity to have lucid dreams is a trainable cognitive skill. During a lucid dream, the dreamer may gain some amount of volitional control over the dream characters, narrative, or environment, although this control of dream content is not the salient feature of lucid dreaming. An important distinction is that lucid dreaming is a distinct type of dream from other types of dreams such as prelucid dreams and vivid dreams, although prelucid dreams are a precursor to lucid dreams, and lucid dreams are often accompanied with enhanced dream vividness. Lucid dreams are also a distinct state from other lucid boundary sleep states such as lucid hypnagogia or lucid hypnopompia.
A dream is a succession of images, ideas, emotions, and sensations that usually occur involuntarily in the mind during certain stages of sleep. Humans spend about two hours dreaming per night, and each dream lasts around 5–20 minutes, although the dreamer may perceive the dream as being much longer than this.
Maslow’s hierarchy of needs is a conceptualisation of the needs that motivate human behaviour, which was proposed by the American psychologist Abraham Maslow. According to Maslow’s original formulation, there are five sets of basic needs that are related to each other in a hierarchy of prepotency. Typically, the hierarchy is depicted in the form of a pyramid although Maslow was not himself responsible for the iconic diagram. The pyramid begins at the bottom with physiological needs and culminates at the top with self-actualization needs. In his later writings, Maslow added a sixth level of ‘meta-needs’ and metamotivation.
Rapid eye movement sleep is a unique phase of sleep in mammals and birds, characterized by random rapid movement of the eyes, accompanied by low muscle tone throughout the body, and the propensity of the sleeper to dream vividly. The core body and brain temperatures increase during REM sleep and skin temperature decreases to lowest values.
Physiological psychology is a subdivision of behavioral neuroscience that studies the neural mechanisms of perception and behavior through direct manipulation of the brains of nonhuman animal subjects in controlled experiments. This field of psychology takes an empirical and practical approach when studying the brain and human behavior. Most scientists in this field believe that the mind is a phenomenon that stems from the nervous system. By studying and gaining knowledge about the mechanisms of the nervous system, physiological psychologists can uncover many truths about human behavior. Unlike other subdivisions within biological psychology, the main focus of psychological research is the development of theories that describe brain-behavior relationships.
Non-rapid eye movement sleep (NREM), also known as quiescent sleep, is, collectively, sleep stages 1–3, previously known as stages 1–4. Rapid eye movement sleep (REM) is not included. There are distinct electroencephalographic and other characteristics seen in each stage. Unlike REM sleep, there is usually little or no eye movement during these stages. Dreaming occurs during both sleep states, and muscles are not paralyzed as in REM sleep. People who do not go through the sleeping stages properly get stuck in NREM sleep, and because muscles are not paralyzed a person may be able to sleepwalk. According to studies, the mental activity that takes place during NREM sleep is believed to be thought-like, whereas REM sleep includes hallucinatory and bizarre content. NREM sleep is characteristic of dreamer-initiated friendliness, compared to REM sleep where it is more aggressive, implying that NREM is in charge of simulating friendly interactions. The mental activity that occurs in NREM and REM sleep is a result of two different mind generators, which also explains the difference in mental activity. In addition, there is a parasympathetic dominance during NREM. The reported differences between the REM and NREM activity are believed to arise from differences in the memory stages that occur during the two types of sleep.
A false awakening is a vivid and convincing dream about awakening from sleep, while the dreamer in reality continues to sleep. After a false awakening, subjects often dream they are performing their daily morning routine such as showering or eating breakfast. False awakenings, mainly those in which one dreams that they have awoken from a sleep that featured dreams, take on aspects of a double dream or a dream within a dream. A classic example in fiction is the double false awakening of the protagonist in Gogol's Portrait (1835).
In the field of psychology, the subfield of oneirology is the scientific study of dreams. Research seeks correlations between dreaming and knowledge about the functions of the brain, as well as an understanding of how the brain works during dreaming as pertains to memory formation and mental disorders. The study of oneirology can be distinguished from dream interpretation in that the aim is to quantitatively study the process of dreams instead of analyzing the meaning behind them.
Self-actualization, in Maslow's hierarchy of needs, is the highest personal aspirational human need in the hierarchy. It represents where one's potential is fully realized after more basic needs, such as for the body and the ego, have been fulfilled. Long received in psychological teaching as the peak of human needs, Maslow later added the category self-transcendence.
Psychoanalytic dream interpretation is a subdivision of dream interpretation as well as a subdivision of psychoanalysis pioneered by Sigmund Freud in the early 20th century. Psychoanalytic dream interpretation is the process of explaining the meaning of the way the unconscious thoughts and emotions are processed in the mind during sleep.
Charcot–Wilbrand syndrome (CWS) is dream loss following focal brain damage specifically characterised by visual agnosia and loss of ability to mentally recall or "revisualize" images. The name of this condition dates back to the case study work of Jean-Martin Charcot and Hermann Wilbrand, and was first described by Otto Potzl as "mind blindness with disturbance of optic imagination". MacDonald Critchley, former president of the World Federation of Neurology, more recently summarized CWS as "a patient loses the power to conjure up visual images or memories, and furthermore, ceases to dream during his sleeping hours". This condition is quite rare and affects only a handful of brain damage patients. Further study could help illuminate the neurological pathway for dream formation.
The expectation fulfilment theory of dreaming, proposed by psychologist Joe Griffin in 1993, posits that the prime function of dreams, during REM sleep, is to act out metaphorically non-discharged emotional arousals (expectations) that were not expressed during the previous day. It theorises that excessive worrying arouses the autonomic nervous system, which increases the need to dream during REM sleep. This deprives the individual of the refreshment of the mind and body brought about by regenerative slow-wave sleep.
Schema therapy was developed by Jeffrey E. Young for use in the treatment of personality disorders and other chronic conditions such as long-term depression, anxiety, and eating disorders.
Secondary consciousness is an individual's accessibility to their history and plans. The ability allows its possessors to go beyond the limits of the remembered present of primary consciousness. Primary consciousness can be defined as simple awareness that includes perception and emotion. As such, it is ascribed to most animals. By contrast, secondary consciousness depends on and includes such features as self-reflective awareness, abstract thinking, volition and metacognition. The term was coined by Gerald Edelman.
The activation-synthesis hypothesis, proposed by Harvard University psychiatrists John Allan Hobson and Robert McCarley, is a neurobiological theory of dreams first published in the American Journal of Psychiatry in December 1977. The differences in neuronal activity of the brainstem during waking and REM sleep were observed, and the hypothesis proposes that dreams result from brain activation during REM sleep. Since then, the hypothesis has undergone an evolution as technology and experimental equipment has become more precise. Currently, a three-dimensional model called AIM Model, described below, is used to determine the different states of the brain over the course of the day and night. The AIM Model introduces a new hypothesis that primary consciousness is an important building block on which secondary consciousness is constructed.
An anxiety dream is an unpleasant dream which can be more disturbing than a nightmare. Anxiety dreams are characterized by the feelings of unease, distress, or apprehension in the dreamer upon waking. Anxiety dreams tend to occur in rapid eye movement sleep, and usual themes involve incomplete tasks, embarrassment, falling, getting in to legal or financial trouble, failed pursuits and being pursued by another, often an unrealistic entity but other human beings can also be the pursuer. Anxiety dreams may be caused by childhood trauma, or an adult dealing with conflict. Though they create anxiety in the dreamer, anxiety dreams also serve as a way for a person's ego to reset.
Antti Revonsuo is a Finnish cognitive neuroscientist, psychologist, and philosopher of mind. His work seeks to understand consciousness as a biological phenomenon. He is one of a small number of philosophers running their own laboratories.
Human Givens is a niche theory in psychotherapy proposed by Joe Griffin and Ivan Tyrrell in the late 1990s, and amplified in the 2003 book Human Givens: A new approach to emotional health and clear thinking. Human Givens therapy draws on several psychotherapeutic models, such as motivational interviewing, cognitive behavioural therapy, psychoeducation, interpersonal therapy, imaginal exposure therapy and NLP such as the Rewind Technique.
Emotions play a key role in overall mental health, and sleep plays a crucial role in maintaining the optimal homeostasis of emotional functioning. Deficient sleep, both in the form of sleep deprivation and restriction, adversely impacts emotion generation, emotion regulation, and emotional expression.
Caetextia is a term and concept first coined by psychologists Joe Griffin and Ivan Tyrrell to describe a chronic disorder that manifests as a context blindness in people on the autism spectrum. It was specifically used to designate the most dominant manifestation of autistic behaviour in higher-functioning individuals. Griffin and Tyrell also suggested that caetextia "is a more accurate and descriptive term for this inability to see how one variable influences another, particularly at the higher end of the spectrum, than the label of 'Asperger's syndrome'".
