STUDY OBJECTIVES: Recurrent nightmares in childhood may have a range of detrimental effects for both the child and parents. This randomized controlled trial evaluated the efficacy of a novel parent-based intervention for childhood nightmares, using a new device called the "Dream Changer." METHODS: A total of 56 children aged 3-10 years (M = 7.1 ± 2.1 years; 51.8% boys), and one of their parents...

Purpose: During the coronavirus disease 2019 (COVID-19) pandemic quarantine, university students were under various types of stressors, including the exams period, which might have affected their quality and quantity of sleep, and consequently, their quality of life. This study aimed to investigate the pattern and predictors of nightmares among university students and coinvestigate the presence...

The continuity hypothesis of dreams suggests that the content of dreams is continuous with the dreamer's waking experiences. Given the unprecedented nature of the experiences during COVID-19, we studied the continuity hypothesis in the context of the pandemic. We implemented a deep-learning algorithm that can extract mentions of medical conditions from text and applied it to two datasets...

Background Trauma experience increases the risk of suicidal ideation, but little is known about potentially psychological mechanisms underlying this relationship. This study aims to examine the relationship between coronavirus disease 2019 (COVID-19)-related traumatic event (CTE) exposure and suicidal ideation among hospital workers, and identify mediating roles of sleep disturbances in this...

Although new learning is known to reappear in later dream scenarios, the timing of such reappearances remains unclear. Sometimes, references to new learning occur relatively quickly, 1 day post-learning (day-residue effect); at other times there may be a substantive delay, 5-7 days, before such references appear (dream-lag effect). We studied temporal delays in dream reactivation following the...

The Coronavirus 2019 pandemic strongly affected our sleep and dream activity. Many cross-sectional studies highlighted increased dream recall frequency, and revealed a great presence of pandemic-related oneiric contents. Here, we present the first prospective study carried out on an Italian sample. One-hundred subjects were requested to fill out a web-survey including socio-demographic...

The effect of cortisol on dreams has been scarcely studied. The aim of this exploratory study was to assess the possible effect of cortisol levels on dream recall/affect, considering, in female subjects, their menstrual cycle phase. Fifteen men and fifteen women were recruited. Saliva samples were used for the detection of cortisol levels. Participants were instructed to provide four saliva...

Nightmares are intense emotional experiences that can greatly alter sleep quality and affect most people at some point in their lives. Yet little research has focused on the relationship between nightmares and the subjective experience of sleep quality. In this study, we aimed at investigating the relationship between nightmare frequency, subjective sleep duration, subjective estimation of...

Despite a surge of studies on the effects of COVID-19 on our well-being, we know little about how the pandemic is reflected in people’s spontaneous thoughts and experiences, such as mind-wandering (or daydreaming) during wakefulness and dreaming during sleep. We investigated whether and how COVID-19 related general concern, anxiety, and daily worry are associated with the daily fluctuation of...

Introduction: While clonidine is used clinically for the treatment of nightmares in posttraumatic stress disorder (PTSD), few case reports demonstrating this indication exist, and there have been few studies investigating clonidine's mechanism of action for controlling nightmare symptoms. Case Report. In order to further characterize clonidine's role in treating nightmare symptoms in PTSD, we...

Objective/background: To describe and characterize insomnia symptoms and nightmare profiles in Portugal during the first six weeks of a national lockdown due to COVID-19. Patients/methods: An open cohort study was conducted to collect information of the general population during the first wave of SARS-CoV-2/COVID-19 pandemic in Portugal. We analyzed data from 5011 participants (≥16 years) who...

When people wake up from a long night sleep, dreams are memorized, sometimes forgotten. What are the factors that influences the clarity and quality of dream recalls when people wake up? Data were collected from the author himself using EEG, survey and introspection. Totally 7 nights of data were collected for this investigation. The results demonstrated borderline negative correlation among...

The mystery of dreams has always been an area of deep research. Lucid dreaming is when people realize they are awake, but they are dreaming. This work introduces and studies the induction methods of lucid dreams. We investigated whether the lucid dream occurred during rapid eye movement and investigated the ability to learn about lucid dreaming. Studies have shown that lucid dreaming has...

Frequent nightmares are highly prevalent and constitute a risk factor for a wide range of psychopathological conditions. Despite its prevalence and clinical relevance however, the pathophysiological mechanisms of nightmares are poorly understood. A recent study (Perogamvros et, al 2019) examined the heart beat evoked potential (HEP) in a small group of nightmare sufferers (N = 11) and matched...

Lucid dreaming is a phenomenon in which the dreamer is aware that he/she is dreaming while the dream is still going on. Many studies investigated the prevalence of lucid dreaming in various populations; however, no study has been conducted in the Arab Middle East region. As age and cultural differences in attitudes towards dreams may influence lucid dreaming, we aimed to investigate lucid...

A growing number of studies have demonstrated that the coronavirus disease-19 (COVID-19) pandemic has severely affected sleep and dream activity in healthy people. To date, no investigation has examined dream activity specifically in COVID-19 patients. As part of the International COVID-19 Sleep Study (ICOSS), we compared 544 COVID-19 participants with 544 matched-controls. A within-subjects...

The waking brain efficiently detects emotional signals to promote survival. However, emotion detection during sleep is poorly understood and may be influenced by individual sleep characteristics or neural reactivity. Notably, dream recall frequency has been associated with stimulus reactivity during sleep, with enhanced stimulus-driven responses in high vs. low recallers. Using...

Several results suggest that the frequency of dream recall is positively correlated with personality traits such as creativity and openness to experience. In addition, neuroimaging results have evidenced different neurophysiological profiles in high dream recallers (HR) and low dream recallers (LR) during both sleep and wakefulness, specifically within regions of the default mode network (DMN)....

Dreams can be affected by recent life events and long-term life experiences. Previous evidence has shown that childhood adverse experiences are associated with sleep quality and dream experiences. The aim of this study was to explore the relationship between childhood adverse experiences and dream content in adults. A total of 163 participants without current or past physical or mental...
