Swapna is a female name, a Hinduphilosophy and the discipline related to dream, dreamwork and dreaming. Swapna in Hindu philosophy is a state of consciousness when a person (or being) is dreaming in sleep. In this state, he or she cannot perceive the external universe with the senses. One enjoys another universe that could have everything that the physical universe contains and more. This universe is created by withdrawing from the physical universe and 'emanating' (Sanskrit: nirmana) in this self-created universe. This universe disappears on waking up to Jagra or slipping on to susupti. This universe is as real to the person who created it (i.e., the dreamer) as the physical universe is real to a waking person. The dreamer has every sense that he can feel in the physical universe, with the same intensity. In terms of psychology, this is the state of consciousness in REM sleep.
