What is sensory deprivation? It is an approach used to elicit an “Out-of-Body Experience”, which typically involves the sensation of floating outside one’s body. When an individual is placed inside a sensory deprivation room or tank, she is isolated from many forms of sensory input all at once. These rooms or tanks are absolutely soundproof and lightproof. The individual undergoes complete quietness that allows her to hear her heart beat, her breath, and the tensing of her muscles. The extreme buoyancy of the water creates an almost zero-gravity environment. The individual becomes one with the room or tank.
Sensory deprivation encourages intense disorientation by removing space and time references. The state of disorientation often permits the individual to experience vivid, spiritual out-of-body experiences. But what happens to people when they are in the experience? Can an isolation room actually transport a person to altered states of consciousness?
