1 Why do we dream? From Freud to random brain activity

2 Mary Calkins - 1893  We dream every night – about 3-4 times a night.  Most dreams are about mundane/everyday things – recent life events. We just tend to remember the more fantastic dreams.  Dreams can incorporate external stimuli – ever had a dream where you really had to go to the bathroom, then woke up and realized you really had to go to the bathroom?

3 Wish Fulfillment  Wish Fulfillment: Freud ’ s idea: dreams are the “ road to the unconscious ” – where our true desires are, so essentially dreams bring out our true desires

4 Content in Dreams  Dreams have manifest content – what the dreamer recalls; and latent content – what the dream really means.  Images generally are symbols for other ideas, but not in every case; analyze the individual and the dream to come up with the meaning

6 Excerpts from Nat Turner ’ s Confessions (1831)  About this time I was placed under an overseer, from whom I ran away and after remaining in the woods thirty days, I returned, to the astonishment of the Negroes on the plantation, who thought I had made my escape to some other part of the country, as my father had done before. But the reason of my return was, that the Spirit appeared to me and said I had my wishes directed to the things of this world, and not to the kingdom of Heaven, and that I should return to the service of my earthly master - "For he who knoweth his Master's will, and doeth it not, shall be beaten with many stripes, and thus have I chastened you." And the Negroes found fault, and murmured against me, saying that if they had my sense they would not serve any master in the world. And about this time I had a vision - and I saw white spirits and black spirits engaged in battle, and the sun was darkened - the thunder rolled in the Heavens, and blood flowed in streams and I heard a voice saying, "Such is your luck, such you are called to see, and let it come rough or smooth, you must surely bare it.

7  And on the 12th of May, 1828, I heard a loud noise in the heavens, and the Spirit instantly appeared to me and said the Serpent was loosened, and Christ had laid down the yoke he had borne for the sins of men, and that I should take it on and fight against the Serpent, for the time was fast approaching when the first should be last and the last should be first.  キ Ques. Do you not find yourself mistaken now?  Ans. Was not Christ crucified? And by signs in the heavens that it would make known to me when I should commence the great work - and until the first sign appeared, I should conceal it from the knowledge of men - And on the appearance of the sign, (the eclipse of the sun last February) I should arise and prepare myself, and slay my enemies with their own weapons.  …

8 Store Memories - Information Processing  REM sleep facilitates memories – without it, we cannot remember things as well. Deep sleep (stage 3 and 4) help to stabilize our memories, and REM sleep helps convert to long-term memories.  Also dreams provide the brain with stimulation, which may assist in strengthening neural pathways.

9  High achieving students on average get 40 more minutes of sleep than low achieving students.

10 Problem Solving - Cognitive Theory  Dreams are generally about what goes on in everyday life, meaning they are most likely dealing with daily problems  Become more complex in adulthood  Dreams often seem to solve personal problems  Example: divorcees as dreamers

11 Scientific Explanation  Activation-Synthesis Theory: dreams are just the result of random brain activity that spreads up from the brainstem, which then activates different parts of the brain responsible for visual images and emotion.

12 Activation Synthesis Theory  Example: paralysis and running during a dream  Admits that everyone ’ s dreams are different because they are influenced by personality and experience
