“…Although interest in the relationship between dreams and psychosis has refluorished in recent research (Scarone et al, 2008; Lusignan et al, 2009; Yu, 2009; Noreika et al, 2010; Schredl, 2011; Zanasi et al, 2011), more experimental data are needed to understand whether or not the abundant findings which have only partially been discussed here can be reconceptualized in a framework linking sleep-dependent processing of memory to the onset of psychotic symptoms in genetically and environmentally predisposed subjects. Similarities and differences in brain function will have to be addressed directly in the future by binding sleep and dream research with research in psychotic disorders within the same experimental framework.…”

“…Although both sides of the equation would not necessarily be equivalent in magnitude, when wake is invaded by more dream-like mentation, dreaming would tend to be permeated by more wake-like, externally oriented thought. The dreams of people with schizophrenia tend to be not as numerous, shorter, less implausible, less emotional, less elaborate, and less self-oriented (Biddle 1963; Hadjez et al 2003; Kramer & Roth 1973), with reduced emotionality both as regards dream content and in terms of the dreamer's expression of emotions (Zanasi et al 2011). Scarone et al (2008) reported that the dreams of people with schizophrenia are as bizarre as the dreams of normal individuals.…”

Such stuff as REM and NREM dreams are made on? An elaboration

This article argues that rapid eye movement (REM) dreaming is elaborative encoding for episodic memories. Elaborative encoding in REM can, at least partially, be understood through ancient art of memory (AAOM) principles: visualization, bizarre association, organization, narration, embodiment, and location. These principles render recent memories more distinctive through novel and meaningful association with emotionally salient, remote memories. The AAOM optimizes memory performance, suggesting that its principles may predict aspects of how episodic memory is configured in the brain. Integration and segregation are fundamental organizing principles in the cerebral cortex. Episodic memory networks interconnect profusely within the cortex, creating omnidirectional "landmark" junctions. Memories may be integrated at junctions but segregated along connecting network paths that meet at junctions. Episodic junctions may be instantiated during non-rapid eye movement (NREM) sleep after hippocampal associational function during REM dreams. Hippocampal association involves relating, binding, and integrating episodic memories into a mnemonic compositional whole. This often bizarre, composite image has not been present to the senses; it is not "real" because it hyperassociates several memories. During REM sleep, on the phenomenological level, this composite image is experienced as a dream scene. A dream scene may be instantiated as omnidirectional neocortical junction and retained by the hippocampus as an index. On episodic memory retrieval, an external stimulus (or an internal representation) is matched by the hippocampus against its indices. One or more indices then reference the relevant neocortical junctions from which episodic memories can be retrieved. Episodic junctions reach a processing (rather than conscious) level during normal wake to enable retrieval. If this hypothesis is correct, the stuff of dreams is the stuff of memory.SUE LLEWELLYN, professor of accountability in the Faculty of Humanities at the University of Manchester, UK, has published widely on the delivery of health services. In recent years she has researched and published on the relationships between REM dreaming, memory processes, and psychopathology.

The analogy between dreams and the ancient art of memory is tempting but superficial

Although the analogy between dreams and ancient mnemotechniques is tempting because they share several phenomenological characteristics, this analogy is superficial at a closer look. Unlike mneomotechnically encoded material, rapid eye movement (REM) dreams are inherently difficult to remember, do not usually allow conscious subsequent retrieval of all interconnected elements, and have been found to support subsequent episodic memory in only rare cases.
