(Sanskrit स्वप्न, literally "dream, sleep, drowsiness, sloth, indolence") A state of dreaming or sleeping consciousness, one of the states of consciousness described in the Hindu scripture Mandukya Upanishad.
"Avasthas or states of consciousness are three: Jagrat (waking), Svapna (dreaming), Sushupti (deep sleep)." —Swami Sivananda
"That state in which objects are perceived through the impressions produced during waking state is called Svapna or dreaming state. The consciousness of the subtle, inner, subjective Prapancha or world, which during the quiescence of the sense-organs arises in the form of the percipient and object of perception by virtue of the latent impressions of what is seen and heard in Jagrat is Svapna." —Swami Sivananda
"I too am deluded in this way, O almighty Lord, foolishly thinking my body, children, home, wife, money and followers to be real, though they are actually as unreal as a dream (svapna)." —Śrīmad Bhagavatam 10.40.24
