I understand that there are phenomenological and neurobiological similarities between the dream state and positive psychopathological state of schizophrenia or psychosis in general. Any fresh perspectives on this?

In any case it would be useful to read something about the bionian view of dream by Ogden, a very famous psychoanalyst. Shortly, dream would be a processing of daily impressions provisorily stored as non linkable elements ( beta elements ) in global ideo-sensory elements ( alpha elements), and in elaborating them. This would be a continous process, not conscious in awake state. Psychotic patients would be impaired in this kind of operation of storage and elaboration. Then psychosis, from this point of view would be not like a dream but the lack of a dream giving sense to sensorial impressions of the patient. Indeed psychotic ideation often looks like dreams. Maybe it s a bundle of dreams not dreamt.
