Dreaming, one of the Four States of Consciousness. It is the state in which atman (the Supreme Self) is mainly misidentified with pranamaya kosha (the “sheath composed of life force”) and manomaya kosha (the “sheath composed of mind”). Thus, the jiva (soul) travels in the cognitive world (the imaginative world of dreams), becomes one with that realm, and loses the consciousness of atman (pure subjectivity). Sometimes while in svapna, atman is misidentified with vijnanamaya kosha (the “sheath composed of intellectual knowledge and understanding”) and then there are lucid dreams. In the dream state, the jiva is caught up with internal objects and loses sight of its true nature as pure “subject.”
