Answer to Question 2
One theory, proposed by Hartmann, is that dreaming allows us to sort through potential solutions to everyday problems and worries. Alternatively, dreaming may provide an opportunity to consolidate memories and new learning from the previous day. Another theory, the activation-synthesis hypothesis, suggests that dreams are the result of the cerebral cortex attempting to organize and interpret the random discharges of neural activity that occur during REM sleep. A more psychological theory of dreaming comes from Sigmund Freud. He contended that dreams are a
form of wish fulfillment, providing an outlet for our sexual and aggressive urges that we cannot normally express. The true meaning of a dream is revealed in its symbolic, or latent, content.
