http://en.wikipedia.org/wiki/Dream

In 1977 J. Allan Hobson and Robert McCarley proposed a new theory that changed dream research, it challenged the previously held Freudian view of dreams as subconscious wishes to be interpreted. The activation synthesis theory asserts that the sensory experiences are fabricated by the cortex as a means of interpreting chaotic signals from the pons. They propose that in REM sleep, the ascending cholinergic PGO (ponto-geniculo-occipital) waves stimulate higher midbrain and forebrain cortical structures, producing rapid eye movements. The activated forebrain then synthesizes the dream out of this internally generated information. They assume that the same structures that induce REM sleep also generate sensory information.[6] Memory, attention and the other features lacking in the dream state are taken to depend on the neurotransmitters, norepinephrine and serotonin, which are present in reduced concentrations during REM sleep. This chemical change is hypothesized to produce a psychotic state, as well as a lack of orientation.
