Oceanic boundlessness

A research term for an experience of unity, timelessness, positive mood, and softened boundaries between self and surroundings. It can occur in altered states but is not specific to breathwork. The term comes from the Swiss researcher Adolf Dittrich's questionnaire on altered states and is still used in psychedelic research. Its name echoes the oceanic feeling described by Romain Rolland and Sigmund Freud. Such experiences are often described as positive, but they vary greatly from person to person.
