Sensory deprivation is the deliberate reduction or removal of stimuli from one or more of the senses. Simple devices such as blindfolds and earmuffs can cut off sight and hearing, while more complex devices can also cut off the sense of smell, touch, taste, thermoception (heat-sense), and 'gravity'. Sensory deprivation has been used in various alternative medicines and in psychological experiments (e.g., see Isolation tank), and for torture or punishment.
Though short periods of sensory deprivation can be relaxing, extended deprivation can result in extreme anxiety, hallucinations, bizarre thoughts, depression, and antisocial behavior.
Chillin in that Sensory deprivation tank took me on a good trip.
