Questo articolo mira ad un’analisi del fenomeno del sogno lucido nelle sue linee teoriche e nelle sue implicazioni pratiche. L’obiettivo è quello di esaminare gli sviluppi attuali e passati del concetto e delinearne le sue possibili applicazioni. Innanzitutto si analizzeranno le prime osservazioni che hanno portato ad un iniziale interesse per il fenomeno nella cultura occidentale, fino alla...

Consciousness is subjective experience. During both sleep and anesthesia, consciousness is common, evidenced by dreaming. A defining feature of dreaming is that, while conscious, we do not experience our environment; we are disconnected. Besides inducing behavioral unresponsiveness, a key goal of anesthesia is to prevent the experience of surgery (connected consciousness), by inducing either...

Sleep paralyses are viewed as pure motor phenomena featured by a dissociated state in which REM-related muscle atonia coexists with a wakefulness state of full consciousness. We present a 59-year-old man diagnosed with narcolepsy experiencing sleep paralysis, who failed to establish the boundaries between real experience and dream mentation during the paralysis: the patient's recall was indeed...

Abnormalities in the sleep/wake cycle and within sleep itself have extensively been studied in a broad range of psychiatric and neurodegenerative disorders. Despite increasing evidence for a mechanistic overlap between the disruptions of circadian timing control and neuropathology, the relationship remains unclear (Wulff et al., 2010). One possible way to address this problem from a psychiatric...

Sleep research is also about the fascination with dreams and consciousness. The current issue of the Journal of Sleep Research contains papers relevant to evolving research trends in this area. Collecting dream reports after induced or spontaneous awakenings is a standard approach in dream research. This approach has established that dreams occur primarily, but not exclusively, during...

Intrinsic and historical weaknesses delayed the spread of a sound neurobiological investigation on dreaming. Nevertheless, recent independent findings confirm the hypothesis that the neurophysiological mechanisms of encoding and recall of episodic memories are largely comparable across wakefulness and sleep. Brain lesion and neuroimaging studies converge in indicating that...

Standard accounts of delusion explain them as responses to experience. Cognitive models of feature binding in the face recognition systems explain how experiences of mismatch between feelings of "familiarity" and faces can arise. Similar mismatches arise in phenomena such as déjà and jamais vu in which places and scenes are mismatched to feelings of familiarity. These cognitive models also...

Dreaming and waking are two brain-mind states, which are characterized by shared and differentiated properties at the levels of brain and consciousness. As part of our effort to capitalize on a comparison of these two states we have applied Edelman's distinction between primary and secondary consciousness, which we link to dreaming and waking respectively. In this paper we examine the...

Dream is a state of consciousness characterized by internally-generated sensory, cognitive and emotional experiences occurring during sleep. Dream reports tend to be particularly abundant, with complex, emotional, and perceptually vivid experiences after awakenings from rapid eye movement (REM) sleep. This is why our current knowledge of the cerebral correlates of dreaming, mainly derives from...

Several independent lines of research in neurobiology seem to support the phenomenologically-grounded view of the dreaming brain/mind as a useful model for psychosis. Hallucinatory phenomena and thought disorders found in psychosis share several peculiarities with dreaming, where internally generated, vivid sensorimotor imagery along with often heightened and incongruous emotion are paired with...
