RESUMO

Dreams can be seen as a way of letting your mind wander while you're awake, an act of imagination that occurs during sleep, or a more or less chimerical imaginary representation of what you ardently hope for. In all three cases, it questions both our relationship with reality (what exists in itself) and with reality (what I perceive and understand of reality). From this point of view, dreams and madness are undeniably two experiences that radically question our access to reality.

RESUMO

While we dream during sleep, our psyche gives free rein to its imagination during waking phases. During nursing interviews, should the patient be allowed to mobilize this imaginative capacity? One answer may come from the Palo Alto school of thought, which uses the imagination in a relational space, so that it becomes an active element in psychic change. In the practice of mental health nursing, it is possible to mobilize this imaginative part, supported by brief therapies, and turn it into a therapeutic path.

RESUMO

Emotions experienced within sleep mentation (dreaming) affect mental functioning in waking life. There have been attempts at enhancing dream emotions using olfactory stimulation. Odors readily acquire affective value, but to profoundly influence emotional processing, they should bear personal significance for the perceiver rather than be generally pleasant. The main objective of the present sleep laboratory study was to examine whether prolonged nocturnal exposure to self-selected, preferred ambient room odor while asleep influences emotional aspects of sleep mentation and valence of post-sleep core affect. We asked twenty healthy participants (12 males, mean age 25 ± 4 years) to pick a commercially available scented room diffuser cartridge that most readily evoked positively valenced mental associations. In weekly intervals, the participants attended three sessions. After the adaptation visit, they were administered the odor exposure and odorless control condition in a balanced order. Participants were awakened five minutes into the first rapid eye movement (REM) stage that took place after 2:30 a.m. and, if they had been dreaming, they were asked to rate their mental sleep experience for pleasantness, emotional charge, and magnitude of positive and negative emotions and also to evaluate their post-sleep core affect valence. With rs < 0.20, no practically or statistically significant differences existed between exposure and control in any outcome measures. We conclude that in young, healthy participants, the practical value of olfactory stimulation with self-selected preferred scents for enhancement of dream emotions and post-sleep core affect valence is very limited.

RESUMO

The ability to forget fear-inducing situations is essential for adapting to our environment, but the neural mechanisms underlying 'fear forgetting' remain unclear. Novel findings reveal that the activity of the infralimbic cortex - specifically during REM sleep - contributes to the extinction of fear memory.

RESUMO

Sleepwalking and related parasomnias result from incomplete awakenings out of non-rapid eye movement sleep. Behavioral episodes can occur without consciousness or recollection, or in relation to dream-like experiences. To understand what accounts for these differences in consciousness and recall, here we recorded parasomnia episodes with high-density electroencephalography (EEG) and interviewed participants immediately afterward about their experiences. Compared to reports of no experience (19%), reports of conscious experience (56%) were preceded by high-amplitude EEG slow waves in anterior cortical regions and activation of posterior cortical regions, similar to previously described EEG correlates of dreaming. Recall of the content of the experience (56%), compared to no recall (25%), was associated with higher EEG activation in the right medial temporal region before movement onset. Our work suggests that the EEG correlates of parasomnia experiences are similar to those reported for dreams and may thus reflect core physiological processes involved in sleep consciousness.

RESUMO

Dreaming is a universal human behavior that has inspired searches for meaning across many disciplines including art, psychology, religion, and politics, yet its function remains poorly understood. Given the suggested role of sleep in emotional memory processing, we investigated whether reported overnight dreaming and dream content are associated with sleep-dependent changes in emotional memory and reactivity, and whether dreaming plays an active or passive role. Participants completed an emotional picture task before and after a full night of sleep and they recorded the presence and content of their dreams upon waking in the morning. The results replicated the emotional memory trade-off (negative images maintained at the cost of neutral memories), but only in those who reported dreaming (Dream-Recallers), and not in Non-Dream-Recallers. Results also replicated sleep-dependent reductions in emotional reactivity, but only in Dream-Recallers, not in Non-Dream-Recallers. Additionally, the more positive the dream report, the more positive the next-day emotional reactivity is compared to the night before. These findings implicate an active role for dreaming in overnight emotional memory processing and suggest a mechanistic framework whereby dreaming may enhance salient emotional experiences via the forgetting of less relevant information.

RESUMO

Suicide is prevalent among young adults, and epidemiological studies indicate that insomnia, nightmares, and depression are significantly associated with a high incidence of suicidal ideation (SI). However, the causal relationship between these factors and SI remains unclear. Therefore, the purpose of this study was to examine the association between nightmares and depression and insomnia and SI in young adults, as well as to develop a mediation model to investigate the causal relationship between insomnia, nightmare, depression, and SI. We assessed insomnia, nightmares, depression, and SI in 546 young adults using the Insomnia Severity Scale (ISI), Disturbing Dream and Nightmare Severity Scale (DDNSI), Depression Study Scale (CESD-20), and Columbia-Suicide Severity Rating Scale (C-SSRS). Using the Bootstrap method, the mediation effects of nightmares and depression between insomnia and SI were calculated. The results demonstrated that nightmares and depression fully mediated the relationship between insomnia and SI, including the chain-mediation of insomnia and SI between nightmare and depression with an effect value of 0.02, 95% CI 0.01-0.04, and depression as a mediator between insomnia and SI with an effect value of 0.22, 95% CI 0.15-0.29. This study found that depression and nightmares may be risk and predictive factors between insomnia and SI, which implies that the assessment and treatment of depression and the simple or linked effect of nightmares play crucial roles in preventing SI in young adults.

RESUMO

Research has posited that social media use during the day may be reflected in nighttime dreams. Nevertheless, no prior studies have explored frightening, unpleasant dreams arising from social media use. This study introduces the construct of the social media-related nightmare by (a) developing and validating a scale capturing negative-valenced dreams with themes of helplessness, loss of control, inhibition, victimization, and making mistakes in social media, and (b) examining relationships between social media use, social media-related nightmares, sleep quality, and affective well-being. A convenience sample of 595 Iranian adult social media users (Mage = 27.45, SDage = 11.42) reported on social media-related nightmare, social media use integration, anxiety, peace of mind, sleep quality, and nightmare distress. The Social Media-Related Nightmare Scale (SMNS) demonstrated a unidimensional structure with sound psychometric properties. The most common nightmares involved the inability to log in to social media and the disruption of relationships with other users. Social media use intensity predicted frequency of social media-related nightmares. These nightmares were correlated with increased anxiety, lower peace of mind, poor sleep quality, and nightmare distress. Importantly, social media-related nightmares mediated the relationship between social media use intensity and low affective well-being (i.e., anxiety and peace of mind), poor sleeping, and nightmare distress. The findings suggest that social media-related nightmares could be a potential pathway through which social media engagement may lead to affective distress and sleep difficulties.

RESUMO

STUDY OBJECTIVES: To identify the distinct classification of insomnia symptoms and to explore their association with sleep problems and depression. METHODS: Latent profile analysis was used to examine patterns of insomnia symptoms in two samples. Discovery and replication samples comprised 1043 (Mean age at baseline = 18.95 ± 0.93 years, 62.2% females) and 729 (Mean age at baseline = 18.71 ± 1.02 years, 66.4% females) college students, respectively. Participants completed measures of sleep problems (insomnia symptoms, sleep quality, susceptibility to insomnia, perceived consequences of insomnia, dream recall frequency, and percentage of recurring nightmares) and other psychological variables (rumination and depression). Binary logistic regression was used to analyze the effects of different types of insomnia symptoms at baseline on sleep problems and depression two years later. RESULTS: Four classes of insomnia symptoms were identified, and classified as "non-insomnia" (class 1, 45.7%), "mild subjective symptoms but severe subjective feelings" (class 2, 23.9%), "severe subjective symptoms but mild subjective feelings" (class 3, 22.0%), and "high insomnia risk" (class 4, 8.4%), respectively. Compared with the group classified as non-insomnia group, other classifications significantly predicted insomnia two years later, only class 4 significantly predicted depression, and class 3 significantly predicted susceptibility to insomnia, after adjusting gender, insomnia, depression, and susceptibility to insomnia at baseline. CONCLUSIONS: The findings highlighted the importance of identifying the patterns of insomnia symptoms, and the need for tailored intervention to improve sleep problems. Additionally, when screening for insomnia symptoms, simplified screening using Insomnia Severity Index (ISI) dimensions or items should be considered.

RESUMO

Nightmares are vivid, extended, and emotionally negative or negative dreams that awaken the dreamer. While sporadic nightmares and bad dreams are common and generally harmless, frequent nightmares often reflect underlying pathologies of emotional regulation. Indeed, insomnia, depression, anxiety, or alcohol use have been associated with nightmares in epidemiological and clinical studies. However, the connection between nightmares and their comorbidities are poorly understood. Our goal was to examine the genetic risk factors for nightmares and estimate correlation or causality between nightmares and comorbidities. We performed a genome-wide association study (GWAS) in 45,255 individuals using a questionnaire-based assessment on the frequency of nightmares during the past month and genome-wide genotyping data. While the GWAS did not reveal individual risk variants, heritability was estimated at 5%. In addition, the genetic correlation analysis showed a robust correlation (rg > 0.4) of nightmares with anxiety (rg = 0.671, p = 7.507e-06), depressive (rg = 0.562, p = 1.282e-07) and posttraumatic stress disorders (rg = 0.4083, p = 0.0152), and personality trait neuroticism (rg = 0.667, p = 4.516e-07). Furthermore, Mendelian randomization suggested causality from insomnia to nightmares (beta = 0.027, p = 0.0002). Our findings suggest that nightmares share genetic background with psychiatric traits and that insomnia may increase an individual's liability to experience frequent nightmares. Given the significant correlations with psychiatric and psychological traits, it is essential to grow awareness of how nightmares affect health and disease and systematically collect information about nightmares, especially from clinical samples and larger cohorts.

RESUMO

BACKGROUND: Emotional processing and regulation of affect are often impaired in psychiatric patients. Nightmares could be considered a manifestation of problems with this process. In the present study, we examined how depression, anxiety and suicidal risk related to difficulties in emotion regulation and nightmares over the course of inpatient treatment. We also explored whether emotion regulation problems moderated the relationship between changes in depression, anxiety, and suicide risk to changes in nightmares from admission to discharge. METHODS: The present study included 1215 adults admitted to an inpatient psychiatric hospital ranging from 18 to 87 years of age (M = 37.18, SD = 16.14). Mood symptoms, emotion regulation difficulties, nightmares and suicide risk were assessed at admission and discharge. Moderation analyses were calculated using Model 1 of the PROCESS Macro (Hayes, 2013). RESULTS: Moderation analyses showed the associations between depression and nightmares (b = 0.25, p < .001) and suicide and nightmares (b = 0.34, p < .001) were strongest when patients had high levels of emotion regulation difficulties. Emotion regulation difficulties did not, however, moderate the relationship between anxiety and nightmares. Furthermore, improvement in depression and nightmares was significantly related to improvement in emotion regulation difficulties. LIMITATIONS: The homogeneity of the sample limits the generalizability of the results. Furthermore, the use of self-report measures, especially sleep related assessments, can bias the data more than objective measures. CONCLUSIONS: These findings provide clinical implications when treating psychiatric patients such as a need for emotion regulation skills building.

RESUMO

Nightmare disorder is characterized by dysfunctional emotion regulation and poor subjective sleep quality reflected in pathophysiological features such as abnormal arousal processes and sympathetic influences. Dysfunctional parasympathetic regulation, especially before and during rapid eye movement (REM) phases, is assumed to alter heart rate (HR) and its variability (HRV) of frequent nightmare recallers (NM). We hypothesized that cardiac variability is attenuated in NMs as opposed to healthy controls (CTL) during sleep, pre-sleep wakefulness and under an emotion-evoking picture-rating task. Based on the polysomnographic recordings of 24 NM and 30 CTL participants, we examined HRV during pre-REM, REM, post-REM and slow wave sleep, separately. Additionally, electrocardiographic recordings of resting state before sleep onset and under an emotionally challenging picture-rating task were also analyzed. Applying repeated measures analysis of variance (rmANOVA), a significant difference was found in the HR of NMs and CTLs during nocturnal segments but not during resting wakefulness, suggesting autonomic dysregulation, specifically during sleep in NMs. As opposed to the HR, the HRV values were not significantly different in the rmANOVA in the two groups, implying that the extent of parasympathetic dysregulation on a trait level might depend on the severeness of dysphoric dreaming. Nonetheless, in the group comparisons, the NM group showed increased HR and reduced HRV during the emotion-evoking picture-rating task, which aimed to model the nightmare experience in the daytime, indicating disrupted emotion regulation in NMs under acute distress. In conclusion, trait-like autonomic changes during sleep and state-like autonomic responses to emotion-evoking pictures indicate parasympathetic dysregulation in NMs.

RESUMO

The development of the concept of dreams in interwar Polish psychiatry and psychology was influenced by Western European concepts as well as by sociocultural factors of the newly independent state. Few Polish psychiatrists addressed the subject of dreams. They were influenced mainly by Sigmund Freud's psychoanalytic concept of dreams, but also by Alferd Adler's, Carl Gustav Jung's, and Wilhelm Stekel's ideas. Nevertheless, they approached psychoanalysis critically. The most comprehensive concept of dreams in Polish psychiatry was oneiroanalysis by Tadeusz Bilikiewicz. Oneironalysis was a method of dream analysis based on psychoanalysis but it rejected the psychoanalytic method of free associations and challenged psychoanalytic approaches to the interpretation of dream symbols. Polish psychologists were even less interested in dreams than psychiatrists. Problems with dreams, the most elaborate psychological work by Stefan Szuman consisted of an outline of epistemological problems with general theories of dreams and a harsh critique of psychoanalysis. The neglect of the subject of dreams in Polish psychiatric society can be seen as connected with the social and professional reception of psychoanalysis in Poland. Psychoanalysis was met with opposition from conservative scholars and publicists presenting nationalistic and anti-Semitic attitudes. It was also criticized by the biologically oriented majority of psychiatrists of the Polish Psychiatric Association. In the case of psychology, the most influential Polish psychological school, Lvov-Warsaw School, promoted Brentanian intentionalism, introspection, and psychology of consciousness, therefore, leading to psychologists' reluctance to explore unconscious states like dreams.

RESUMO

Research on aspects of dreaming associated with alexithymia has yielded mixed results. The present study recruited a young adult online sample of 577 participants who completed validated indices of alexithymia, emotion suppression, negative moods, and eight aspects of dreaming, with a focus on evaluating a counterintuitive previous finding that alexithymia and two of its core facets were associated with greater self-reported typical emotional intensity of dreams. Total alexithymia and facet scores showed differential relationships to aspects of dreaming including dream recall frequency, emotionality, meaningfulness, nightmare frequency, nightmare distress, usefulness of dreams in problem-solving and creativity, and learning about oneself through dreams. Planned hierarchical regression controlling for demographics, alcohol use, and dream recall frequency indicated that the difficulties identifying feelings (DIF) facet of alexithymia was a significant positive predictor of dream emotionality, whereas the externally oriented thinking (EOT) facet was a significant negative predictor. Stress, but not emotion suppression, mediated the positive relationship between DIF and dream emotionality. The likely role of dream emotionality in higher ratings of nightmare distress, dream meaningfulness, and learning about oneself through dreams among those with higher DIF scores is noted, along with other findings and the strengths and limitations of the study.

RESUMO

When we are confronted with the challenge of trying to fully convey or describe something about human life and emotional experience, we find ourselves up against the very limitations of language. This problem becomes especially relevant as we attempt to expand psychoanalytic theory so as to enable us to "approach a mental life unmapped by the theories elaborated for the understanding of neurosis" (Bion1962, p. 37). This paper seeks to aid in that expansion by revisiting Bion's early writings about the beta screen, extending his conclusions about communication from the psychotic part of the mind to the broad area of the unrepresented (the unstructured unconscious), suggesting that there is often a potentially communicative meaning, a mute plea for intersubjective regulatory assistance (alpha function), embedded in the unconscious evocation of emotions in the object and that this cry for help may be encrypted in even the most seemingly destructive, resistant and oppositional patients.

RESUMO

Until recently, understanding the neurobiology of dreaming has relied upon on correlating a subjective dream report with a measure of brain activity or function sampled from a different occasion. As such, most assumptions about dreaming come from the neuroscience of rapid eye-movement (REM) sleep from which many, but not all, dream reports are recalled. Core features of REM sleep (intense emotional activation, a reduction in activity in most frontal regions, particularly the dorsolateral prefrontal cortex, along with increased dopamine, acetylcholine, cholinergic activation) align with typical dream characteristics (characterised by fear, reduced reality monitoring, increased bizarreness and hyperassociativity, respectively). The default mode network offers a way of understanding the nature of dreaming more independently from a REM sleep context, and electroencephalography methods paired with serial awakenings to elicit dream reports demonstrate how high-frequency activity in posterior regions may be associated with dreaming. Nevertheless, all measures of dreaming rely fundamentally on recall processes, so our understanding of dreaming must embrace and address memory's crucial involvement in dream report production.

RESUMO

OBJECTIVE: Nightmares are dysphoric dreams present in both clinical and non-clinical populations. Physiological activity underlies their emotional reactivity. Therefore, the objective of this study was to investigate the role of interoceptive processes (interoceptive sensibility and nociception) in nightmares in the general population. METHOD: 542 French participants were recruited from the general population to complete an online survey. Interoceptive sensibility, nociception, nightmare frequency and nightmare distress were assessed through online scales and questionnaires. Network analysis, regression and mediation analyses were conducted to assess the relationship between these variables. RESULTS: The results showed the existence of associations between certain dimensions of interoceptive sensibility, nociception, nightmare frequency and nightmare distress. The regression analysis highlighted the involvement of interoceptive dimensions in predicting the nightmare distress score. Mediation analysis highlighted that nociception was a mediating variable in the relationship between nightmare frequency and nightmare distress. CONCLUSION: This study provides initial evidence in favour of the involvement of interoceptive processes in the understanding of nightmares. These results offer a new window of understanding the etiology of nightmares but also present the interest to target interoceptive processes in the management of nightmares.

RESUMO

The hypnagogic state refers to the transitional phase between wakefulness and sleep during which vivid experiences occur. In this questionnaire study, we assessed the self-reported prevalence of hypnagogic states considering the frequency of experiences in different modalities. We also assessed the emotional quality and the vividness of the experiences. Moreover, we compared hypnagogic states to other phenomena, such as dreams, sleep paralysis, imagination, and extra-sensory perception in these measures. Hypnagogic states were reported by 80.2 % of 4456 participants and were more prevalent in women than men. Experiences were most often kinaesthetic and visual, and less often auditory, tactile, and olfactory or gustatory. Hypnagogic states were less prevalent than dreams and characterized by different modality profiles. However, they were similar to dreams in their emotional quality, the irritation they caused, and in their vividness. In conclusion, hypnagogic states are quite common.
