Why do we dream?

Seminar paper from the year 2010 in the subject English Language and Literature Studies - Other, grade: 1,7, University of Osnabrck, course: Forging the American Mind - Literature, Philosophy and the Anticipation of Cognitive Science, language: English, abstract: Dreams can be seen as subjective phenomena that only become realities if we can
remember their contents after waking. But how many of you remember your dreams and why
do we dream at all? - The first question can easily be answered: About 80% according to the
statistics (Jouvet 27). The answer to the second question, however, has puzzled humankind
for a long time and even today scientists do not agree on one explicit theory.
In my term paper I will present various answers to the question of dreaming given by
different dream analysts. At first, I will give a short historical overview on the role of dreams
and how they have been seen in different societies. Whereas the Ancient Egypt and the bible
attributed a supernatural element to dreams, Aristotle introduced the psychological character
of dreams.
The main work of my paper will be the analysis of three major perspectives on dream
theories: The psychoanalytical, the biological, and the cognitive perspective. Freud argued
that dreams express unconscious desires and underlying wishes which he termed the latent
content. In contrast, Hobson & McCarley believe that dreams are created because of random
activity in the brain during a certain state of sleep (REM). More recent studies done by
Stickgold try to be more precise. He argues that the brain is active during sleep because it tries
to identify new connections to learn new things from old memory.
In a final step, I will apply the different dream theories on a dream from the movie
"Requiem for a Dream" (USA, 2000) in order to outline and compare their main features and
to show what a dream can tell us about the personality and the life of the dreamer according to
the three perspectives.
