Recently, the construct ‘lucid dreamless sleep’ has been proposed to explain the state of ‘clear light’ described by Tibetan Buddhist traditions, a special state of consciousness during deep sleep in which we’re told to be able to recognise the nature or essence of our mind (Padmasambhava & Gyatrul 2008; Ponlop 2006; Wangyal 1998). To explain the sort of awareness experienced during this state, some authors have appealed to the sort of lucidity acquired during lucid dreaming and suggested a (...) link between both phenomena (Thompson 2014, 2015; Windt 2015a; Windt et al. 2016). Whilst these authors appeal to a non-conceptually mediated form of lucidity, which doesn’t consist of reflective awareness and propositional thought, the question as to whether the state of clear light should be considered a lucid state similar to lucid dreaming still arises. I argue that the concept ‘lucidity’ used to describe this sort of state is imprecise and that two theoretical notions of lucidity should be distinguished. The first one, which I call the technical notion, requires the recognition of the hallucinatory character of my current experience. The second, the broader notion, involves the seeming recognition of being directly acquainted with the phenomenal character of my experience. I spell out these two notions of lucidity and argue that only the latter could apply to the state of clear light sleep. (shrink)

Within the community of inquiry literature, the absence of the notion of genuine doubt is notable in spite of its pragmatic roots in the philosophy of Charles Sanders Peirce, for whom the notion was pivotal. We argue for the need to correct this oversight due to the educational significance of genuine doubt—a theoretical and experiential understanding of which can offer insight into the interrelated concepts of wonder, fallibilism, inquiry and prejudice. In order to detail these connections, we reinvigorate the ideas (...) of Peirce by borrowing the language and concepts of Albert Camus, at the same time demonstrating their unlikely congruence. In particular, we argue for the necessity of genuine doubt along with the need for the presence of a diversity of prejudices as a starting point for genuine inquiry. (shrink)

Lucid dreaming provides a test case for theories of dreaming. For example, whether or not “loss of self-reflective awareness” is characteristic of dreaming, it is not necessary to dreaming. The fact that lucid dreamers can remember to perform predetermined actions and signal to the laboratory allows them to mark the exact time of particular dream events, allowing experiments to establish precise correlations between physiology and subjective reports, and enabling the methodical testing of hypotheses. [Hobson et al.; Solms].

Lucid dreaming refers to a dream state characterized by the dreamers awareness of being in a dream and being able to volitionally control its content. The aim of this study was to find neurophysiological evidence for the 7 criteria of lucid dreaming proposed by Paul Tholey. Each of the criteria was analyzed separately with regard to its underlying neurocircuits. We hypothesized that not one, but many regions are involved in the state of lucid dreaming. Our results have (...) shown a satisfactory overlap of the theoretical components and the brain regions activated during a lucid dream. During lucid dreaming, a brain network seems to emerge, that is more than the sum of its parts. Further research is needed to understand the psychoneurological underpinnings of lucid dreams.

Lucid dreams are dreams in which a person becomes aware that they are dreaming. They are different from ordinary dreams, not just because of the dreamer's awareness that they are dreaming, but because lucid dreams are often strikingly realistic and may be emotionally charged to the point of elation. Celia Green and Charles McCreery have written a unique introduction to lucid dreams that will appeal to the specialist and general reader alike. The authors explore the experience of (...) lucid dreaming, relate it to other experiences such as out-of-the-body experiences and apparitions, and look at how lucid dreams can be induced and controlled. They explore their use for therapeutic purposes such as counteracting nightmares. Their study is illustrated throughout with many case histories. (shrink)

Evidence of reflective awareness and metacognitive monitoring during REM sleep dreaming poses a significant challenge to the commonly held view of dream cognition as necessarily deficient relative to waking cognition. To date, dream metacognition has not received the theoretical or experimental attention it deserves. As a result, discussions of dream cognition have been underrepresented in theoretical accounts of consciousness. This paper argues for using a converging measures approach to investigate the range and limits of cognition and metacognition across the sleep–wakefulness (...) cycle. The paradigm developed by LaBerge and his colleagues to study "lucid-control" dreaming offers one such framework for relating phenomenological, cognitive, and physiological measures. In a lucid-control dream, the dreamer is both aware that the experimental context is a dream and has the ability to intentionally regulate aspects of the dream . Subjects can make patterns of deliberate eye movements to signal from the dream and thus index significant events such as the time of lucidity onset and the completion of previously agreed-upon tasks in the dream. Lucid dreaming and other examples of reflective awareness during dreaming have important implications for models of human cognition. The existence of these phenomena raises fundamental questions about current assumptions regarding "state" constraints on consciousness and cognition. (shrink)

This study investigated the relationship between dream lucidity, i.e., a dreamer’s insight to the ongoing dream, and attention by considering lucidity as a trait. We examined the ways in which lucidity correlates with the orienting, alerting, and conflict components of the attentional network. A total of 77 participants rated the lucidity of their dreams over 7 consecutive days with the LuCiD scale and then completed the attentional network task. A negative correlation between trait lucidity and the conflict score of (...) the ANT was found for 49 participants whose responses were faster when an alerting signal was presented. This result suggested that, with a prerequisite that the presence of cues facilitates subsequent information processing, the greater a person’s trait lucidity, the more efficiently he or she is capable of resolving conflicts.

Activity in the prefrontal cortex may distinguish the meta-awareness experienced during lucid dreams from its absence in normal dreams. To examine a possible relationship between dream lucidity and prefrontal task performance, we carried out a prospective study in 28 high school students. Participants performed the Wisconsin Card Sort and Iowa Gambling tasks, then for 1 week kept dream journals and reported sleep quality and lucidity-related dream characteristics. Participants who exhibited a greater degree of lucidity performed significantly better on the (...) task that engages the ventromedial prefrontal cortex, but degree of lucidity achieved did not distinguish performance on the task that engages the dorsolateral prefrontal cortex, nor did it distinguish self-reported sleep quality or baseline characteristics. The association between performance on the Iowa Gambling Task and lucidity suggests a connection between lucid dreaming and ventromedial prefrontal function. (shrink)

In lucid dreams the dreamer is aware of dreaming and often able to influence the ongoing dream content. Lucid dreaming is a learnable skill and a variety of techniques is suggested for lucid dreaming induction. This systematic review evaluated the evidence for the effectiveness of induction techniques. A comprehensive literature search was carried out in biomedical databases and specific resources. Thirty-five studies were included in the analysis , of which 26 employed cognitive techniques, 11 external stimulation and (...) one drug application. The methodological quality of the included studies was relatively low. None of the induction techniques were verified to induce lucid dreams reliably and consistently, although some of them look promising. On the basis of the reviewed studies, a taxonomy of lucid dream induction methods is presented. Several methodological issues are discussed and further directions for future studies are proposed.

In simple terms, psychological dualism purports that there is an underlying complementary, non-material/physical cognitive component associated with a living organism. Thus mind would not simply be an expression of brain function. Science embraces materialism and generally views any form of dualism with disdain. Yet there are a number of accepted phenomena that are suggestive of dualism and in particular are consistent with the existence of souls. One such phenomenon is terminal lucidity, in which people inexplicably return to mental coherence shortly (...) before death after appearing to be lost to “dull, unconscious, or mentally ill” conditions, sometimes for years. The physical/neural plausibility of such rejuvenation is difficult to imagine. Discussions herein introduce terminal lucidity primarily based on some clinal reports. Next, the medium-based communications reviewed in Chris Carter’s Science and the After Life Experience are used to introduce the concept of a soul. Further, a dynamic suggested in Carter’s coverage is then used to offer a simple explanation for terminal lucidity. Finally, for additional context, the state of neuroscience is considered and some brief conclusions are given. (shrink)

What could it mean to be conscious in your dreams? For most of us, dreaming is something quite separate from normal life. When we wake up from being chased by a ferocious tiger, or seduced by a devastatingly good-looking Nobel Prize winner we realize with relief or disappointment that "it was only a dream.".

Throughout, there are many case histories to illustrate the text.

Near the end of Plato’s Republic iv, Socrates reveals that the justice discovered externally in the city is a phantom of justice, as opposed to the justice discovered internally in the individual, which is justice in truth (443b7-444a2). This paper explains the distinction between true justice and its phantom, as well as the significance of this distinction to the underlying argument of Plato’s Republic.

The struggle to become lucid is at the heart of The Myth of Sisyphus. To understand the absurd is to understand that the fit between our conception of the world and the world itself is fraught with uncertainty; lucidity is the elucidation of the absurd. To be lucid is to revolt against the type of certainty that leads to suffering; to revolt against philosophical suicide. Camus teaches us the intellectual humility that stays hands; there is no reasoning that (...) justifies suffering. If it is granted that the ability to recognise and respond to our own and others suffering is an important part of being human, and the task of education is to develop humans, then lucidity, in so far as it holds promise for the development of such an ability, has the potential to contribute positively to education.

This early essay by Albert Camus presents an eloquent picture of his understanding of what it means to know. But in order for us to assimilate it, we must recognize that Camus is not celebrating a hedonic naturalism, nor engaging in an existential anti-intellectualism. Rather, his articulation of lucidity and the exemplification of it in the artistry of the essay itself presents us with a challenging concept of knowledge. I attempt to explicate this concept with the help of two images, (...) one from the musical Hair and one from the movie The Pawnbroker, thus seeking to reinforce Camus' reliance upon image as the equivalent of idea.

This paper advances reasons why lucid dreaming is considered problematic to the psychoanalytic venture. It is shown that the conscious thought mechanism of lucid dreaming is obstructive and in opposition to the repressed and therefore conflictual within the unconscious parameters. A negative value is attached to the mechanism of lucid dreaming which is presented as an ill-advised endeavor that undermines meaning through its promotion of conscious interference and ego inhibition of dream symbolism. Viewed as a deterrent to (...) self-knowledge and the interpretative process of working through, lucid dreaming does not advance an authentic inner presentation and is therefore of no interest to the betterment of the psyche. At the core of the argument is the significance of the willful autonomy of an ego-conscious presence on the continuance of the dream schematic. (shrink)

Of Jean Baudrillard’s four orders of simulacra: the natural, the commodity, the code, and the fractal the first three have been widely acknowledged, especially the importance of the theory of the third order for his analysis of the Gulf War. But the fourth order has not been accorded similar recognition and his works around this idea are not as widely known. It is clear that his essays on 9/11 drew substantially on ideas rounding out the theory of the fourth order. (...) This article examines the emergence of the radical theory of evil of the later Baudrillard. (shrink)

In this article, we present results from an interdisciplinary research project aimed at assessing consciousness in dreams. For this purpose, we compared lucid dreams with normal non-lucid dreams from REM sleep. Both lucid and non-lucid dreams are an important contrast condition for theories of waking consciousness, giving valuable insights into the structure of conscious experience and its neural correlates during sleep. However, the precise differences between lucid and non-lucid dreams remain poorly understood. The construction (...) of the Lucidity and Consciousness in Dreams scale was based on theoretical considerations and empirical observations. Exploratory factor analysis of the data from the first survey identified eight factors that were validated in a second survey using confirmatory factor analysis: INSIGHT, CONTROL, THOUGHT, REALISM, MEMORY, DISSOCIATION, NEGATIVE EMOTION, and POSITIVE EMOTION. While all factors are involved in dream consciousness, realism and negative emotion do not differentiate between lucid and non-lucid dreams, suggesting that lucid insight is separable from both bizarreness in dreams and a change in the subjectively experienced realism of the dream.

Recent studies suggest that lucid dreaming might be associated with increased brain activity over frontal regions during rapid eye movement sleep. By applying transcranial direct current stimulation , we aimed to manipulate the activation of the dorsolateral prefrontal cortex during REM sleep to increase dream lucidity. Nineteen participants spent three consecutive nights in a sleep laboratory. On the second and third nights they randomly received either 1 mA tDCS for 10 min or sham stimulation during each REM period starting (...) with the second one. According to the participants’ self-ratings, tDCS over the DLPFC during REM sleep increased lucidity in dreams. The effects, however, were not strong and found only in frequent lucid dreamers. While this indicates some preliminary support for the involvement of the DLPFC in lucid dreaming, further research, controlling for indirect effects of stimulation and including other brain regions, is needed.
