A dream character, sometimes abbreviated as DC, is an interactable human-like entity in the person's dream, especially while the person is REM-sleeping. The topic has been profoundly addressed in the lucid dreaming community, since while experiencing a lucid dream, the person can consciously interact with dream characters.
A specific dream character may reappear from dream to dream. [1]
Dream characters may agree or disagree if asked to perform specific tasks. If they agree, they can solve tasks such as rhyming or drawing, although they have relatively poor arithmetical skills. [2]
Furthermore, dream characters have the ability to come up with ways to outwit the dreamer, like switching off the light to avoid his or her gaze. Recurring dream characters can learn from previous dreams and adapt their behaviour accordingly. [2]
The nature of dream characters is subject to debate amongst dream researchers. Some psychotherapists suggest that they represent parts of the dreamer's self. [3]
The hypothesis that dream characters may have a consciousness of their own has been brought forth by some researchers, such as Paul Tholey. Although this hypothesis is impossible to prove, experiments have shown them to have capabilities which suggest that they may have independent points of view and behave like conscious beings. [2]
Consciousness, at its simplest, is awareness of internal and external existence. However, its nature has led to millennia of analyses, explanations and debate by philosophers, theologians, and all of science. Opinions differ about what exactly needs to be studied or even considered consciousness. In some explanations, it is synonymous with the mind, and at other times, an aspect of mind. In the past, it was one's "inner life", the world of introspection, of private thought, imagination and volition. Today, it often includes any kind of cognition, experience, feeling or perception. It may be awareness, awareness of awareness, or self-awareness either continuously changing or not. The disparate range of research, notions and speculations raises a curiosity about whether the right questions are being asked.
In the psychology subfield of oneirology, a lucid dream is a type of dream wherein a person that is dreaming 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 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 to 20 minutes, although the dreamer may perceive the dream as being much longer than this.
Artificial consciousness (AC), also known as machine consciousness (MC), synthetic consciousness or digital consciousness, is the consciousness hypothesized to be possible in artificial intelligence. It is also the corresponding field of study, which draws insights from philosophy of mind, philosophy of artificial intelligence, cognitive science and neuroscience. The same terminology can be used with the term "sentience" instead of "consciousness" when specifically designating phenomenal consciousness.
Dyscalculia is a disability resulting in difficulty learning or comprehending arithmetic, such as difficulty in understanding numbers, learning how to manipulate numbers, performing mathematical calculations, and learning facts in mathematics. It is sometimes colloquially referred to as "math dyslexia", though this analogy is misleading as they are distinct syndromes.
A philosophical zombie is a being in a thought experiment in philosophy of mind that is physically identical to a normal human being but does not have conscious experience.
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 is the double false awakening of the protagonist in Gogol's Portrait (1835).
The somatic marker hypothesis, formulated by Antonio Damasio and associated researchers, proposes that emotional processes guide behavior, particularly decision-making.
A dream diary is a diary in which dream experiences are recorded. A dream diary might include a record of nightly dreams, personal reflections and waking dream experiences. It is often used in the study of dreams and psychology. Dream diaries are also used by some people as a way to help induce lucid dreams. They are also regarded as a useful catalyst for remembering dreams. The use of a dream diary was recommended by Ann Faraday in The Dream Game as an aid to memory and a way to preserve details, many of which are otherwise rapidly forgotten no matter how memorable the dream originally seemed. Keeping a dream diary conditions a person to view remembering dreams as important. Dreams can be recorded in a paper diary or via an audio recording device. Many websites offer the ability to create a digital dream diary.
Dreamwork is the exploration of the images and emotions that a dream presents and evokes. It differs from classical dream interpretation in that it does not attempt to establish a unique meaning for the dream. In this way the dream remains "alive" whereas if it has been assigned a specific meaning, it is "finished". Dreamworkers take the position that a dream may have a variety of meanings depending on the levels that are being explored.
A recurring dream is a dream which is experienced repeatedly over a long period. They can be pleasant or nightmarish and unique to the person and their experiences.
Underlight is a fantasy multiplayer online role-playing game. It was Lyra Studio's first product and launched on MPlayer.com in March 1998. The game is currently managed by KoiWare and was released on Steam in December 2018.
Anomalous experiences, such as so-called benign hallucinations, may occur in a person in a state of good mental and physical health, even in the apparent absence of a transient trigger factor such as fatigue, intoxication or sensory deprivation.
Pre-lucid dreaming is the beginning stages of inducing the lucid dreaming process. At this stage, the dreamer considers the question: "Am I asleep and dreaming?" The dreamer may or may not come to the correct conclusion. Such experiences are liable to occur to people who are deliberately cultivating lucid dreams, but may also occur spontaneously to those with no prior intention to achieve lucidity in dreams.
Paul Tholey was a German Gestalt psychologist, and a professor of psychology and sports science at the University of Frankfurt and the Technical University of Braunschweig.
Primary consciousness is a term the American biologist Gerald Edelman coined to describe the ability, found in humans and some animals, to integrate observed events with memory to create an awareness of the present and immediate past of the world around them. This form of consciousness is also sometimes called "sensory consciousness". Put another way, primary consciousness is the presence of various subjective sensory contents of consciousness such as sensations, perceptions, and mental images. For example, primary consciousness includes a person's experience of the blueness of the ocean, a bird's song, and the feeling of pain. Thus, primary consciousness refers to being mentally aware of things in the world in the present without any sense of past and future; it is composed of mental images bound to a time around the measurable present.
Cognitive skills, also called cognitive functions, cognitive abilities or cognitive capacities, are skills of the mind, as opposed to other types of skills such as motor skills. Some examples of cognitive skills are literacy, self-reflection, logical reasoning, abstract thinking, critical thinking, introspection and mental arithmetic. Cognitive skills vary in processing complexity, and can range from more fundamental processes such as perception and various memory functions, to more sophisticated processes such as decision making, problem solving and metacognition.
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.
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.
