Altered States of Consciousness
Psychedelics, near-death experiences, dreams, meditation, hypnosis, flow states, and sensory deprivation — altered states as windows into the structure of consciousness.
Altered states of consciousness reveal that ordinary waking awareness is not the only mode of conscious experience. By studying psychedelics, near-death experiences, lucid dreaming, deep meditative states, hypnosis, and flow, researchers gain insight into how consciousness can be transformed — and what this tells us about its fundamental nature.
