A "Psychonaut" is a person who explores altered states of consciousness, often through the use of substances like psychedelics or meditation. The term combines "psycho," relating to the mind, and "naut," meaning sailor or explorer. Psychonauts seek to understand the mind, consciousness, and the nature of reality. Many psychonauts document their experiences to share insights about perception, spirituality, and mental health. This exploration can involve both personal reflection and scientific inquiry, contributing to fields like transpersonal psychology and neuroscience. The practice emphasizes safety, intention, and respect for the substances used.
