Time appears to slow down during meditation and dreaming compared to objective clock time, based on introspective self-observation by the author. The work uses the phenomenological approach of perception to explore subjective and objective time, comparing personal experience with clock measurements. The findings highlight the complex and interconnected nature of time perception in human consciousness.

Consciousness can persist, transform, and dissolve across wakefulness, sleep, and advanced meditation. An interdisciplinary perspective reveals converging phenomena that challenge binary accounts of consciousness and highlight its graded, dynamic, and trainable nature. The interface of advanced meditation, sleep, and consciousness science constitutes a promising frontier for understanding the structure, dynamics, and limits of conscious experience. Advanced meditation offers cultivable means for modulating these dimensions, while sleep provides recurring biological states in which awareness, experiential content, embodiment, and sensory input coupling systematically dissociate. Evidence from these domains highlights states such as deep absorption meditation, cessations, lucid dreaming, sleep-wake transitions, and clear light sleep that challenge binary distinctions between consciousness and unconsciousness. An integrated, mixed-methods perspective enables a more nuanced examination of graded and minimal forms of conscious experience.

A 48-year-old Japanese man with severe chronic primary low back pain reported over 360 dreams during insight-oriented psychotherapy from 2009 to 2025. In 2014, he received five low-dose intravenous ketamine infusions (15 mg; 0.23 mg/kg) and described a void-like dissociative state during the first session. After coding a random subset of 50 dreams, obstruction decreased from pre- to post-ketamine periods (treating clinician: 6/9 vs 4/30; external psychiatrist: 6/9 vs 7/30), while a social-interaction/role-completion motif increased post-ketamine (2/9 pre; 10/30 and 11/30 post). Dream content shifted from recurrent obstruction toward imagery of movement, interpersonal engagement, and everyday role completion. These hypothesis-generating observations describe ketamine-associated phenomenology and longitudinal dream-content change without making efficacy claims.

A new composite index that combines three properties of brain activity—scale-free temporal organization, cross-frequency organization, and metastable flexibility in large-scale synchronization—separates conscious from non-conscious synthetic brain states without overlap and distinguishes wakefulness from N2 and REM sleep in 30 healthy adults using two-channel EEG recordings. The index captures organized dynamical complexity rather than raw signal complexity alone and remains stable across sensitivity and Monte Carlo analyses. The framework is not tied to any single theory of consciousness and may be applicable to anesthesia, disorders of consciousness, and basic consciousness research.

Dream weaving among the Blaan and T'boli peoples of Mindanao, Philippines, is a tradition in which t'nalak textile designs are believed to be bestowed by divine spirits in dreams, forming a social-moral and spiritual consciousness that provides identity and social cohesion. This cultural analysis compares Filipino concepts such as Kapwa (shared identity) and Loob (relational will) to Western sociological theories including Geertz's ideology as a cultural system, Durkheim's collective consciousness, and the sociology of knowledge and power. The paper also draws parallels with Native American dream frameworks, where dreams are a source of divine inspiration, and advocates for social consciousness as an approach to religion, contrasting "way of life" with the "supernatural."

Psychosis may leave a person's core cognitive architecture intact while altering how they attribute reality to their experiences. Drawing on predictive processing, dreaming, and the Cognitive Languages framework, this hypothesis argues that the subjective experience of psychosis reflects the brain's existing representational systems rather than an entirely new way of thinking. The paper offers several testable predictions meant to guide future empirical research in computational psychiatry, cognitive neuroscience, and mechanism-based mental health treatment.

A folk tale about a magical ruler that heals and revives the dead is analyzed through a shamanic lens. The ruler acts as an axis mundi, a spiritual bridge connecting heaven and earth, guiding the soul back to the body. The tale's narrative follows shamanic initiation: a mysterious dream (supernatural calling), imprisonment and symbolic death, learning healing from animals (shamanic education), and reviving a princess to gain communal recognition. Similar shamanic elements appear in related tales, where powers like healing and understanding animals reflect traditional shamanic abilities. The study argues that shamanism, as a primordial system of thought, forms a foundational cultural framework underlying many folk narratives.

Mediumistic experiences—reports of communicating with spirits, ancestors, or other nonordinary beings—are vivid, culturally powerful, and ontologically disputed. This review proposes the Principle of Explanatory Sequence: investigate such contested experiences by moving from careful description through phenomenological, cultural, psychological, biological, and historical analyses before making ontological claims. A companion principle, Explanatory Conservation, holds that later explanations should not erase earlier phenomenological evidence. Drawing on predictive processing, embodied cognition, neuroanthropology, and other fields, the review argues mediumistic experience emerges from interactions among neurobiology, culture, ritual, personal history, and interpretation. It does not prove or disprove spirits but clarifies what different forms of evidence can and cannot support, concluding that these experiences expose the limits of explanation itself.

A pilot study tested whether targeted dream incubation (TDI) at sleep onset can direct dream content into subsequent REM sleep. Eleven participants received verbal prompts about a tree and were awakened serially at sleep onset, then during a daytime nap. All 11 successfully incubated the target theme at sleep onset. Of the eight who entered REM sleep, four (50%) incorporated the tree into their first REM dream, and five (63%) did so in later REM dreams. Results suggest TDI may influence REM dream content, offering a method to explore how dream generation and function may be continuous or differ across sleep stages.

Motor learning in sports benefits from both physical practice and sleep-dependent memory consolidation. Waking motor imagery engages brain networks similar to actual movement, while slow-wave sleep and REM sleep support procedural memory through neural replay. Lucid dreaming—awareness during sleep—may allow mental rehearsal that partially reactivates prefrontal regions and shows physiological correlates of dreamed movement. Preliminary evidence suggests lucid dream practice can improve waking performance comparably to waking mental practice. It offers a low-physical-load tool for rehabilitation, tapering, and pre-competition stress management, though low lucid dream frequency, variable induction reliability, and few controlled trials in elite athletes call for cautious use.
