Dreams have a foresight function, enabling us to find a way out of an immediate conflict. [I 2] To reduce the polysemy of the term, Jung sometimes speaks of the "intuitive function" of dreams. [G 3] This prospective function is not in fact a premonitory dream, but teaches the dreamer a path to follow. [2]
This was perceived as the activation-synthesis model, stating that brain activation during REM sleep results in synthesis of dream creation. [1] Hobson's five cardinal characteristics include: intense emotions, illogical content, apparent sensory impressions, uncritical acceptance of dream events, and difficulty in being remembered. [6]
Dream imagery can change quickly and is regularly of a bizarre nature, but reports also contain many images and events that are a part of day-to-day life. [9] In dreams there is a reduction or absence of self-reflection or other forms of meta-cognition relative to during waking life. [5]
Freud believed that dreams were messages from the unconscious masked as wishes controlled by internal stimuli. The unconscious mind plays the most imperative role in dream interpretation. In order to remain in a state of sleep, the unconscious mind has to detain negative thoughts and represent them in any edited form.
Most modern dream study focuses on the neurophysiology of dreams and on proposing and testing hypotheses regarding dream function. It is not known where in the brain dreams originate, if there is a single origin for dreams or if multiple regions of the brain are involved, or what the purpose of dreaming is for the body or mind.
Psychoanalytic dream interpretation is the process of explaining the meaning of the way the unconscious thoughts and emotions are processed in the mind during sleep. There have been a number of methods used in psychoanalytic dream interpretation, including Freud's method of dream interpretation, the symbolic method, and the decoding method.
This includes the activation synthesis theory—the theory that dreams result from brain stem activation during REM sleep; the continual activation theory—the theory that dreaming is a result of activation and synthesis but dreams and REM sleep are controlled by different structures in the brain; and dreams as excitations of long-term memory ...
Research into dreams includes exploration of the mechanisms of dreaming, the influences on dreaming, and disorders linked to dreaming. Work in oneirology overlaps with neurology and can vary from quantifying dreams to analyzing brain waves during dreaming, to studying the effects of drugs and neurotransmitters on sleeping or dreaming.
