ABSTRACT
From the viewpoint of modern psychology there are several 'states' of awareness including sleep, dreaming, the hypnotic trance, lucid dreaming and even coma. This may seem rather more science fiction than scientific psychology, and it does not demonstrate what or where consciousness actually is, but it does indicate that consciousness is complex and involves more than the hindbrain, and possibly involves communication between the left and right hemispheres. Some psychologists have suggested that there are three levels of consciousness: conscious, pre-conscious and unconscious. The most obvious states of consciousness are being awake and being asleep. Yet now there are literally thousands of such articles, showing the explosion of interest in this state of consciousness. Fie proposed three levels of awareness as follows: Oakley argued that consciousness requires a highly developed brain and that self-awareness requires an even more highly developed cortex.
