Dream production is not chaotic

The AIM model proposed by Hobson et al. is interesting: We know the neuroph ysiological aspects of the activation process (A) and the external input (I ), but very little about the internal input and neurocognitive process (M). Internal input could he an expression of unconscious experiences memorised lib the subject containing his emotional and cognitive history. Therefore internal input could not be chaotic but might have an emotional and affecti ve sense bound to the unconscious. The fact that dreams are present in the absence of REM sleep means that they may originate from other structures be sides the pons. These structures may represent the archives of dreamer's af fective history.
