Altered States Of Consciousness by Marc Wittmann

Experiences Out of Time and Self

An accessible exploration of how varied mental states—from sleep and dreaming to meditation, psychedelics, hypnosis, flow, and psychiatric conditions—transform the senses of self and time. Integrating neuroscience, psychology, and vivid case studies, it explains how bodily signals and brain networks construct consciousness, why time dilates or vanishes, and what ego dissolution, dissociation, near-death experiences, and timelessness reveal about the mind.
