Document Summary
Hypnagogic state: the transitional state from wakefulness through early stage 2 sleep; as this state continues, mental activity become more dreamlike. Most take place in familiar settings and often involve people we know. Blissful dreaming: most people have dreamed of flying. Freud"s psychoanalytic theory: main purpose of dreaming is wish fulfillment, the gratification of our unconscious desires and needs, including sexual and aggressive urges that are too unacceptable to be consciously acknowledged and fulfilled in real life. Manifest content: the surface story that the dreamer reports. Activation component: during rem sleep the brain stem bombards our higher brain centers with random neural activity. Synthesis component: cerebral cortex continues to interpret by creating a dream that provides the best fit to the particular pattern of activation that exists at any particular moment. Brain is trying to make sense out of random neural activity.
