The Dreamachine is a light-based art installation created by Brion Gysin and William S. Burroughs in the 1960s. It consists of a cylindrical device that spins and emits flickering light patterns, designed to induce altered states of consciousness when viewed with closed eyes. The experience is often described as a form of visual meditation. The Dreamachine operates on the principle of stroboscopic light, which stimulates the brain's visual cortex. Participants typically sit in a dark room, allowing the light to create vivid imagery and sensations. This unique experience has been explored in various artistic and therapeutic contexts, highlighting its potential for creativity and introspection.
