Awareness in the void: a micro-phenomenological exploration of conscious dreamless sleep

This paper presents a pilot study that explores instances of objectless awareness during sleep: conscious experiences had during sleep that prima facie lack an object of awareness. This state of objectless awareness during sleep has been widely described by Indian contemplative traditions and has been characterised as a state of consciousness-as-such; while in it, there is nothing to be aware of, one is merely conscious (cf. Evans-Wentz, 1960; Fremantle, 2001; Ponlop, 2006). While this phenomenon has received different names in the literature, such as ‘witnessing-sleep’ and ‘clear light sleep’ among others, the specific phenomenological profile of this state has not yet been rigorously studied. This paper aims at presenting a preliminary investigation of objectless consciousness during sleep using a novel tool in qualitative research that can guide future research. Five participants experiencing objectless consciousness during sleep were interviewed following the Micro-phenomenological Interview technique (MPI; Petitmengin, 2005, 2006). All participants reported an experience they had during sleep in which there was no scenery and no dream. This period labelled as ‘No Scenery/Void’ was either preceded by the dissolution of a lucid dream or by other forms of conscious mentation. The analysis of the results advances four experiential dimensions during this state of void, namely (1) Perception of absence, (2) Self-perception, (3) Perception of emotions, and (4) Perception of awareness. While the results are primarily explorative, they refer to themes found in the literature to describe objectless sleep and point at potential avenues of research. The results from this study are taken as indications to guide future operationalisations of this phenomenon.

Leibniz and the ‘petites réflexions’

In this article, I defend the thesis that Leibniz’s rational substances always have higher-order perceptions, even when they are, say, in a dreamless sleep. I argue that without this assumption, Leibniz’s conception of reflection would introduce discontinuities into his philosophy of mind which (given his Principle of Continuity) he cannot allow. This interpretation does not imply, however, that rational beings must be aware of these higher-order states at all times. In fact, these states are often unconscious or ‘small’ (analogous to Leibniz’s famous petites perceptions) and only count as reflections when they become distinct or heightened enough. Reflections thus arise out of ‘petites réflexions’ just as conscious perceptions arise out of petites perceptions. I argue, furthermore, that an analysis of some aspects of Leibniz’s theory of memory shows that he is not only committed to the thesis that rational beings always have higher-order states but that he also accepts it. I conclude by considering whether my interpretation is at odds with Leibniz’s doctrine of transcreation and also whether it has any consequences for which theory of consciousness we should ascribe to Leibniz.

Zur subjektlosen Souveränität des traumlosen Schlafs: Dissoziation, Trauma und Erwachen bei Perec und Moshfegh

Much has been written about dreaming, but deep, dreamless sleep still seems to receive little attention within cultural studies and social science. This article analyses Georges Perec's A Man Who Sleeps and Ottessa Moshfegh's My Year of Rest and Relaxation in terms of the phantasm of metamorphosis enabled by sleep. These two novels show that the polarity of waking and dreaming can be relativized and shifted to the polarity between waking-dreaming/sleeping: This shift becomes particularly productive when it comes to the question of losing and finding ones identity, but also when we try to shed light on the relationship between (ideological or biographical) subjectification and self-overcoming. At the centre of this article is the notion of the sovereignty of sleep, which could allow both day life and dream life to be lifted out of joint.

The Diagonal Argument Strikes Again: Why Physical Systems Can Never Be Sure

Chalmers has described the meta-problem of consciousness as the problem of understanding how and why we come to believe that we are conscious. Here we show that the meta-problem of consciousness is intimately related to another problem; the meta-problem of existence, or the problem of understanding how and why we come to believe that we exist. This problem is shown to lead to a version of Russell's paradox which makes it impossible for any physical system ever to be sure that it exists. The problem is illustrated by a thought experiment, the "sleepwalker paradox", which shows that no physical system can ever be sure that it is not in a dreamless sleep.

Dreamless Sleep, the Embodied Mind, and Consciousness: The Relevance of a Classical Indian Debate to Cognitive Science

One of the major debates in classical Indian philosophy concerned whether consciousness is present or absent in dreamless sleep. The philosophical schools of Advaita Vedānta and Yoga maintained that consciousness is present in dreamless sleep, whereas the Nyāya school maintained that it is absent. Consideration of this debate, especially the reasoning used by Advaita Vedānta to rebut the Nyāya view, calls into question the standard neuroscientific way of operationally defining consciousness as “that which disappears in dreamless sleep and reappears when we wake up or dream.” The Indian debate also offers new resources for contemporary philosophy of mind. At the same time, findings from cognitive neuroscience have important implications for Indian debates about cognition during sleep, as well as for Indian and Western philosophical discussions of the self and its relationship to the body. Finally, considerations about sleep drawn from the Indianmaterials suggest that we need a more refined taxonomy of sleep states than that which sleep science currently employs, and that contemplative methods of mind training are relevant for advancing the neurophenomenology of sleep and consciousness.

Dreams, agency, and judgement

Sosa (Proc Addresses Am Philos Assoc 79(2): 7–18, 2005) argues that we should reject the orthodox conception of dreaming—the view that dream states and waking states are “intrinsically alike, though different in their causes and effects” (2005: p. 7). The alternative he proposes is that “to dream is to imagine” (2005: p. 7). According to this imagination model of dreaming, our dreamt conscious beliefs, experiences, affirmations, decisions and intentions are not “real” insofar as they are all merely imagined beliefs, experiences, affirmations, decisions and intentions. This paper assesses the epistemic implications of Sosa’s imagination model of dreaming. Section 1 outlines and assesses the reasons Sosa gives for thinking that his imagination model of dreaming introduces a new dimension to debates about dream scepticism. Sosa argues that his imagination model of dreaming invites a more radical version of dream scepticism, and also makes available a novel and more powerful response to dream scepticism. Objections are raised to both of those claims. This leads to a challenge to Sosa’s imagination model of dreaming. This is the concern that Sosa’s imagination model of dreaming lacks the resources to accommodate the intuition that there is something illusory or misleading about one’s situation when one is dreaming, and as a result his account of dreams fails to accommodate the common intuition that there is a sceptical problem about dreaming but not about dreamless sleep. Section 2 of the paper elaborates a version of the imagination model of dreaming that can overcome that challenge. This version of the imagination model of dreaming goes beyond what Sosa explicitly commits to when he outlines his view of dreams, however, it exploits ideas that are integral to a key theme in Sosa’s recent writings on virtue reliabilism—namely his proposal that epistemic agency should be accorded a central place in that approach to knowledge, and his related proposal that agency is exercised in conscious judgement. An implication of this version of the imagination model of dreaming is that an elucidation of a connection between the wakeful condition and our capacity to exercise agency over our mental lives should be central to an account of the nature, and epistemic significance of, wakeful consciousness. The final section of the paper considers whether this version of the imagination model of dreaming has anything novel to contribute to debates about dream scepticism.
