What altered states of consciousness—the dissolution of feelings of time and self—can tell us about the mystery of consciousness. During extraordinary moments of consciousness—shock, meditative states and sudden mystical revelations, out-of-body experiences, or drug intoxication—our senses of time and self are altered; we may even feel time and self dissolving. These experiences have long been ignored by mainstream science, or considered crazy fantasies. Recent research, however, has located the neural underpinnings of these altered states of mind. In this book, neuropsychologist Marc Wittmann shows how experiences that disturb or widen our everyday understanding of the self can help solve the mystery of consciousness. Wittmann explains that the relationship between consciousness of time and consciousness of self is close; in extreme circumstances, the experiences of space and self intensify and weaken together. He considers the emergence of the self in waking life and dreams; how our sense of time is distorted by extreme situations ranging from terror to mystical enlightenment; the experience of the moment; and the loss of time and self in such disorders as depression, schizophrenia, and epilepsy. Dostoyevsky reported godly bliss during epileptic seizures; neurologists are now investigating the phenomenon of the epileptic aura. Wittmann describes new studies of psychedelics that show how the brain builds consciousness of self and time, and discusses pilot programs that use hallucinogens to treat severe depression, anxiety, and addiction. If we want to understand our consciousness, our subjectivity, Wittmann argues, we must not be afraid to break new ground. Studying altered states of consciousness leads us directly to the heart of the matter: time and self, the foundations of consciousness.

Some of our most burning questions surround consciousness: What creates our identity? Do we really have free will? Is consciousness itself an illusion? The rapid rate of developments in brain science continues to open up debate on these issues. This book clarifies the complex arguments and illuminates the major theories on consciousness.

An international collection examining the opportunities for using music-induced states of altered consciousness. The observations of the contributors cover a wide range of music types capable of inducing altered states. It will interest practicing music therapists, musicologists, and ethnomusicologists, students and academics in the field.

Over the last century, developments in electronic music and art have enabled new possibilities for creating audio and audio-visual artworks. With this new potential has come the possibility for representing subjective internal conscious states, such as the experience of hallucinations, using digital technology. Combined with immersive technologies such as virtual reality goggles and high-quality loudspeakers, the potential for accurate simulations of conscious encounters such as Altered States of Consciousness (ASCs) is rapidly advancing. In Inner Sound, author Jonathan Weinel traverses the creative influence of ASCs, from Amazonian chicha festivals to the synaesthetic assaults of neon raves; and from an immersive outdoor electroacoustic performance on an Athenian hilltop to a mushroom trip on a tropical island in virtual reality. Beginning with a discussion of consciousness, the book explores how our subjective realities may change during states of dream, psychedelic experience, meditation, and trance. Taking a broad view across a wide range of genres, Inner Sound draws connections between shamanic art and music, and the modern technoshamanism of psychedelic rock, electronic dance music, and electroacoustic music. Going beyond the sonic into the visual, the book also examines the role of altered states in film, visual music, VJ performances, interactive video games, and virtual reality applications. Through the analysis of these examples, Weinel uncovers common mechanisms, and ultimately proposes a conceptual model for Altered States of Consciousness Simulations (ASCSs). This theoretical model describes how sound can be used to simulate various subjective states of consciousness from a first-person perspective, in an interactive context. Throughout the book, the ethical issues regarding altered states of consciousness in electronic music and audio-visual media are also examined, ultimately allowing the reader not only to consider the design of ASCSs, but also the implications of their use for digital society.

The second edition of this pathbreaking investigation into the nature of cognitive reality explores various manifestations of consciousness, from sleeping and dreaming, to hypnosis, trance, hallucinations, and experiences related to death.

This volume presents various perspectives on altered states of consciousness and mental health and places them within the boundaries of cross-cultural psychology. Part One considers theoretical and methodological issues in the study of altered states of consciousness; Parts Two and Three link altered states of consciousness and mental health by focusing on both its therapeutic and pathological aspects. The final section concentrates on models highlighting a variety of paradigms and diverse methodological approaches.

An investigation into the brain's chemistry and the mechanisms of chemically altered states of consciousness. In this book, J. Allan Hobson offers a new understanding of altered states of consciousness based on knowledge of how our brain chemistry is balanced when we are awake and how that balance shifts when we fall asleep and dream. He draws on recent research that enables us to explain how psychedelic drugs work to disturb that balance and how similar imbalances may cause depression and schizophrenia. He also draws on work that expands our understanding of how certain drugs can correct imbalances and restore the brain's natural equilibrium. Hobson explains the chemical balance concept in terms of what we know about the regulation of normal states of consciousness over the course of the day by brain chemicals called neuromodulators. He presents striking confirmation of the principle that every drug that has transformative effects on consciousness interacts with the brain's own consciousness-altering chemicals. In the section called "The Medical Drugstore," Hobson describes drugs used to counteract anxiety and insomnia, to raise and lower mood, and to eliminate or diminish the hallucinations and delusions of schizophrenia. He discusses the risks involved in their administration, including the possibility of new disorders caused by indiscriminate long-term use. In "The Recreational Drugstore," Hobson discusses psychedelic drugs, narcotic analgesia, and natural drugs. He also considers the distinctions between legitimate and illegitimate drug use. In the concluding "Psychological Drugstore," he discusses the mind as an agent, not just the mediator, of change, and corrects many erroneous assumptions and practices that hinder the progress of psychoanalysis.

In the 1960s, Americans combined psychedelics with Buddhist meditation to achieve direct experience through altered states of consciousness. As some practitioners became more committed to Buddhism, they abandoned the use of psychedelics in favor of stricter mental discipline, but others carried on with the experiment, advancing a fascinating alchemy called psychedelic Buddhism. Many think exploration with psychedelics in Buddhism faded with the revolutionary spirit of the sixties, but the underground practice has evolved into a brand of religiosity as eclectic and challenging as the era that created it. Altered States combines interviews with well-known figures in American Buddhism and psychedelic spirituality—including Lama Surya Das, Erik Davis, Geoffrey Shugen Arnold Sensei, Rick Strassman, and Charles Tart—and personal stories of everyday practitioners to define a distinctly American religious phenomenon. The nuanced perspective that emerges, grounded in a detailed history of psychedelic religious experience, adds critical depth to debates over the controlled use of psychedelics and drug-induced mysticism. The book also opens new paths of inquiry into such issues as re-enchantment, the limits of rationality, the biochemical and psychosocial basis of altered states of consciousness, and the nature of subjectivity.
