Write a 6 page essay on Why And What We Dream.
Dreams are inspirational, spiritual, and fantastical, but they have physiological and psychological causes. The true nature of dreams is unknown, but some of the ideas that have come to be accepted about dreams is based on the purposes of REM sleep. REM sleep, or rapid eye movement sleep in which an observable movement of the eye beneath the lid is associated with dreams, likely helps in the process of memory. REM is associated with the stage of sleep called slow-wave sleep. One of the ways in which dreams can be viewed is the act in which new memories are made more permanent (Nevid, 2009). In this view, the nature of dreams is a processing center in which memories are made more long-term rather than merely short-lived. Although the dream may not be centered on fresh memories, the processing seems to produce a creative production of perceived ideas.
Another very popular view of dreams is called activation-synthesis hypothesis. This hypothesis proposes that “dreams represent an attempt by the cerebral cortex to make sense of the random discharges of electrical activity that occur during REM sleep” (Nevid, 2009, p. 143). Hobson in 198i proposed that the cerebral cortex is sending electrical charges through the brain at this time and the memories that are stored are accessed in order to help process those charges. In this theory, the nature of dreams has a very little meaning other than to act as processing facilitation for the storm of electrical flashes that the cortex is producing.
