“…Using this technique it has been possible to obtain a much wider and more representative sample than had been available on the basis of the spontaneous morning recall of dreams. The night report has proved to be more reliable since even when dreams are reported during the night, part of their content may be forgotten by the next morning (Cicogna, Cavallero & Bosinelli, 1982; Cipolli, Salzarulo & Calabrese, 1981; Goodenough, Lewis, Shapiro, Jaret & Sleser, 1965; Meier, Ruef, Ziegler & Hall, 1968). For these reasons, most experimental studies of dreaming attempt to reconstruct the dream experience on the basis of the night report alone.…”

This paper presents the data obtained when night dream reports, collected by waking subjects during REM sleep, are completed by a complementary morning interview. Our data collection technique aims at facilitating the storage of the dream experience in long-term memory, at assisting in the recall of this experience the next morning and at obtaining a maximum level of information which communicates the contents of the dream as completely as possible. The night and complementary morning reports of 15 subjects (one dream per subject) were analyzed by two judges. Each subject added an important amount of information in the morning interview: on the whole 622 new pieces of information, which contributed to eliminate ambiguities and substantially changed the way in which the experimenters visualized and understood the dream experience. The additional information did not make the contents of the dream more coherent and most of it (78%) could not have been deduced from the elements mentioned in the night report. Specific features of dream mentation also appeared in the additional morning information.

“…Another interesting finding is the lack of differences between CG and PG in the representation of Self and one's own body. This feature has been occasionally described in healthy subjects [38,43,44], with data pointing to the presence of changes in the representation of the Self according to age and to the sleep state from which the dream is recalled (being more similar to wakefulness in REM sleep dreams and more polymorph in NREM sleep dreams). To our knowledge, this is the first time that Self representation is assessed in a clinical population.…”

Dreams and positive symptoms of schizophrenia are similar in many aspects, such as bizarre-ness, impairment of reality testing, intense emotional participation. Hallucinations, delusions, and disorganized thoughts have been proposed to be an intrusion of the dreaming state in wake-fulness: conversely, psychotic patients’ abnormal cognitive and behavioral features could over-flow into sleep, transferring peculiar features to their dreams which would differ, in quantity and quality, from those of healthy people. Here we assess this latter hypothesis by analyzing the dreams of 46 patients, hosted in a residential facility or in a day-treatment center, affected by disorders of the schizophrenic spectrum with psychotic symptoms, versus those of 28 healthy controls, in terms of several quantitative and qualitative characteristics. In patients, we also in-vestigated whether dream variables correlated with the severity of symptoms assessed via the Brief Psychiatric Rating Scale. Overall, patients reported fewer and shorter dreams than controls, with a reduction of many ele-ments like characters and settings. The greatest differences regarded emotions, which were less frequent in patients and inversely correlated with symptoms’ severity. This evidence supports the hypothesis that dreams are crucial for emotion regulation during wakefulness and that this func-tion could be totally or partially ineffective in psychoses.

Positive symptoms of schizophrenia have been proposed to be an intrusion of dreaming in wakefulness; conversely, psychotic patients’ abnormal cognitive and behavioral features could overflow into sleep, so that their dreams would differ from those of healthy people. Here we assess this hypothesis by comparing dream features of 46 patients affected by schizophrenic spectrum disorders to those of 28 healthy controls. In patients, we also investigated correlations of dream variables with symptom severity and verbal fluency. Overall, patients reported fewer and shorter dreams, with a general impoverishment of content (including characters, settings, interactions) and higher spatiotemporal bizarreness. The number of emotions, mainly negative ones, was lower in patients’ reports and correlated inversely with symptom severity. Verbal fluency correlated positively with dream report length and negatively with perceptive bizarreness. In conclusion, our data show a significant impoverishment of dream reports in psychotic patients versus controls. Future research should investigate to what extent this profile of results depends on impaired verbal fluency or on impaired mechanisms of dream generation in this population. Moreover, in line with theories on the role of dreaming in emotion regulation, our data suggest that this function could be impaired in psychoses and related to symptom severity.
