Abstract
Nightmares—vivid, emotionally dysphoric dreams—are quite common and are associated with a broad range of psychiatric conditions. However, the origin of such dreams remains largely unexplained, and there have been no attempts to reconcile repetitive traumatic nightmares with nontraumatic nightmares, dysphoric dreams that do not awaken the dreamer, or with more normative dreams. Based on recent research in cognitive neuroscience, sleep physiology, fear conditioning, and emotional-memory regulation, we propose a multilevel neurocognitive model that unites waking and sleeping as a conceptual framework for understanding a wide spectrum of disturbed dreaming. We propose that normal dreaming serves a fear-extinction function and that nightmares reflect failures in emotion regulation. We further suggest that nightmares occur as a result of two processes that we term affect load—a consequence of daily variations in emotional pressures—and affect distress—a disposition to experience events with high levels of negative emotional reactivity.

Abstract
OBJECTIVE The present study investigated the relationship between daytime symptomatology and nightmare frequency in school-aged children by eliciting daytime symptoms and nightmare frequency from children directly in addition to questionnaires completed by their parents. METHODS A sample of 4,834 parents and 4,531 of their children (age range: 8-11 years) completed each a sleep questionnaire and the strengths and difficulties questionnaire (SDQ). RESULTS The results of the study clearly indicate that there is an underestimation of nightmare frequency in the parents' ratings compared to the children's data (effect size: d = 0.30) and the closeness between influencing factors and nightmare frequency is considerably higher for the data based on the children's responses; the proportion of explained variance was twice as high. CONCLUSIONS Therefore, it seems important for research and clinical practice to not to rely on parents' information but to ask the children about the occurrence of nightmares.

Abstract
Sleep disturbances are often viewed as a secondary symptom of post-traumatic stress disorder (PTSD), thought to resolve once PTSD has been treated. Specific screening, diagnosis and treatment of sleep disturbances is therefore not commonly conducted in trauma centres. However, recent evidence shows that this view and consequent practices are as much unhelpful as incorrect. Several sleep disorders-nightmares, insomnia, sleep apnoea and periodic limb movements-are highly prevalent in PTSD, and several studies found disturbed sleep to be a risk factor for the subsequent development of PTSD. Moreover, sleep disturbances are a frequent residual complaint after successful PTSD treatment: a finding that applies both to psychological and pharmacological treatment. In contrast, treatment focusing on sleep does alleviate both sleep disturbances and PTSD symptom severity. A growing body of evidence shows that disturbed sleep is more than a secondary symptom of PTSD-it seems to be a core feature. Sleep-focused treatment can be incorporated into any standard PTSD treatment, and PTSD research needs to start including validated sleep measurements in longitudinal epidemiologic and treatment outcome studies. Further clinical and research implications are discussed, and possible mechanisms for the role of disturbed (REM) sleep in PTSD are described.

Abstract
This study examines the impact of military trauma on contextualized emotional images in children's dreams, and the function of the intensity and valence of the emotional images in protecting mental health from negative trauma impact. Participants were 345 Palestinian children and adolescents (aged 5—16 years) belonging to high trauma (Gaza) and non-trauma (Galilee) groups. They reported nocturnal dreams using a seven-night dream diary. The results show, as hypothesized, that the dreams of children exposed to severe military trauma incorporated more intense and more negative emotional images. High intensity and low negative, and high positive emotional images in dreams may protect children's mental health. Children in the trauma group showed relatively fewer post-traumatic symptoms if their dreams incorporated intensive and positive emotional images. Similarly, personal exposure to military trauma was not associated with anxiety and aggressiveness among children whose dreams had low negative valence, or with lower anxiety when dreams had intensive emotional images. The emotional qualities of dreams are discussed as possible indicators of children processing their traumatic experiences.

Abstract
Nightmares are a prevalent parasomnia associated with a range of psychiatric conditions and pathological symptoms. Current knowledge about how nightmares are produced is still influenced by neo-psychoanalytic speculations as well as by more recent personality, evolutionary and neurobiological models. A majority of these models stipulate some type of emotionally adaptive function for dreaming, e.g., image contextualization, affect desomatization, mood regulation or fear extinction. Nightmares are widely seen to be either an intensified expression of an emotionally adaptive function or, conversely, as evidence of its breakdown. Our recent, affective network dysfunction (AND) model, integrates the tenets of many prior models in proposing that nightmares reflect problems with the fear extinction function of dreaming. This new model accounts for a wide range of dysphoric dream imagery (bad dreams, idiopathic nightmares, post-traumatic nightmares) and incorporates recent findings in the areas of brain imaging, sleep physiology, PTSD, anxiety disorders and the consolidation and extinction of fear memories.

Abstract
Rapid eye movement sleep behavior disorder (RBD) occurs in approximately one third of patients with Parkinson's disease (PD) and is associated with a loss of muscle atonia during REM sleep and aggressive dream content. We examined the dream characteristics of PD patients to determine whether dream content differed between patients with RBD and without RBD, men and women with RBD, and men and women with PD. One hundred-twenty patients with a diagnosis of idiopathic PD were consecutively recruited from a movement disorders clinic and were assessed for RBD using clinical diagnostic criteria of the International Classification of Sleep Disorders Revised (2001). Verbatim dream content was obtained from each patient and categorized into dream themes that were coded into nominal categories. Fisher's exact tests determined whether particular dreams were correlated with RBD versus non-RBD, men and women with RBD, and men and women with PD. RBD patients had a higher percentage of violent dreams compared to non-RBD patients. There were no significant sex differences in the dream content of RBD patients. Men with PD had more aggressive dreams compared to females with PD. Aggressive dream content was characteristic of RBD patients and sex differences exist in the dream content of the PD population.

Abstract
Many studies have reported positive correlations between dream recall frequency (DRF) and measures of absorption, psychological boundaries and attitude towards dreams. A majority of these studies, however, have relied exclusively on retrospective measures of DRF even though daily dream logs are generally considered to be more direct and valid measures of DRF. The first goal of the present meta-analysis was to evaluate the effect sizes of three variables (absorption, psychological boundaries and attitude towards dreams) as correlates of DRF. The second goal was to evaluate if these effect sizes varied as a function of how DRF was operationalized (i.e. retrospective measure versus dream log). Data from 24 studies were included in the analyses. For each of the three variables investigated, correlations with retrospective measures of DRF were of greater magnitude than those obtained with daily logs. These results indicate that scores on measures of absorption and psychological boundaries are not related to DRF per se, but rather to people's tendency to retrospectively underestimate or overestimate their DRF, while attitude towards dreams is related both to DRF per se and to people's retrospective estimation bias. Implications of these findings for dream research are discussed.

Abstract
BACKGROUND The goal of this pilot study was to evaluate the effects of the cognitive-restructuring technique 'lucid dreaming treatment' (LDT) on chronic nightmares. Becoming lucid (realizing that one is dreaming) during a nightmare allows one to alter the nightmare storyline during the nightmare itself. METHODS After having filled out a sleep and a posttraumatic stress disorder questionnaire, 23 nightmare sufferers were randomly divided into 3 groups; 8 participants received one 2-hour individual LDT session, 8 participants received one 2-hour group LDT session, and 7 participants were placed on the waiting list. LDT consisted of exposure, mastery, and lucidity exercises. Participants filled out the same questionnaires 12 weeks after the intervention (follow-up). RESULTS At follow-up the nightmare frequency of both treatment groups had decreased. There were no significant changes in sleep quality and posttraumatic stress disorder symptom severity. Lucidity was not necessary for a reduction in nightmare frequency. CONCLUSIONS LDT seems effective in reducing nightmare frequency, although the primary therapeutic component (i.e. exposure, mastery, or lucidity) remains unclear.

Abstract
The function of REM sleep dreaming is still unknown. We situate our approach to understanding dream phenomenology and dream function within that part of evolutionary theory known as Costly Signaling Theory (CST). We contend that many of the signals produced by the dreaming brain can be and should be construed as “costly signals”—emotions or mental simulations that produce daytime behavioral dispositions that are costly to the dreamer. For example, often the dreamer will appear in the dream as handicapped in some way (i.e., no clothes, no ID, no money, is under attack, being chased etc.). The dreamer, during waking life, is then influenced by the carry-over effect of the unpleasant dream content. The informational and affective content of the dream creates a mental set in the dreamer that operates during the daytime to facilitate the signaling of a “handicapped” Self. The subtle signaling effect might be via display of the intense emotions or physical demeanor that had first appeared in the dream. When the dreamer shares his dream with others the dream has a more direct impact on waking life and social interactions. In effect, the dreamer uses his or her dreams to adopt a self-handicapping strategy when dealing with significant others. The increased use of costly signals (the self-handicapping strategy) during the daytime then facilitates some vital communicative goal of the dreamer.

Abstract
Parasomnias are undesirable behaviors that arise from sleep but are not fully under voluntary control. Parasomnias are grouped broadly according to whether they arise from non-rapid eye movement (NREM) or rapid eye movement (REM) sleep. NREM parasomnias are disorders of arousal that occur along a continuum of behavioral, affective, and autonomic activation. REM-related parasomnias include REM sleep behavior disorder, sleep paralysis, and nightmare disorder. Parasomnias can often be managed successfully using behavioral and pharmacologic therapies.

Abstract
In the 19th century, several authors held the view that nightmares are caused by oxygen shortage. The present study was designed to study nightmare frequency in patients with obstructive sleep apnea syndrome and its relationship to respiratory parameters. A brief questionnaire was administered to 323 patients with sleep apnea syndrome before their first laboratory night. The reduction in nightmare frequency in the sleep apnea group was explained by the reduced dream recall frequency. Despite some illustrative examples of a correlation between oxygen desaturation and dream content, the respiratory parameters as measures of sleep apnea syndrome severity did not correlate substantially with nightmare frequency. Psychiatric comorbidity and an intake of psychotropic medication were associated with heightened nightmare frequency in this sample. It must be concluded that the oxygen hypothesis did not play a major role in explaining the occurrence of nightmares. As this might be partly explained by adaptation to the nightly desaturation periods, it will be fruitful to apply experimental procedures that interrupt airflow during (rapid eye movement) REM sleep for short periods in a systematic way without the knowledge of the sleeper and to then study their effects on dream content. Some patients reported a correlation between daytime stressors and nightmares, which is in line with modern etiological models of nightmares.

Abstract
Problems with nightmares are reported by a sizable proportion of individuals with a history of trauma and by approximately 5% to 8% of the general population. Chronic nightmares may represent a primary sleep disorder rather than a symptom of a psychiatric disorder, and direct targeting of nightmares is a feasible clinical approach to the problem. Of the treatments proposed, imagery rehearsal therapy (IRT) has received the most empirical support. An up-to-date account of this cognitive-imagery approach shows how to treat nightmares during 4 roughly 2-hr sessions. The main points covered in each therapy session and their underlying rationale are presented. Dismantling protocols are suggested to discern active ingredients of IRT and to develop flexible applications based on patients' needs.

Abstract
This longitudinal study tested the continuity hypothesis, which postulates that waking states and concerns are reflected in dreams. The relationship between dream content and negative waking affect was investigated both at fixed points in time and over a 6- to 10-year period. Twenty-eight participants completed measures of psychological well-being (PWB) and kept a dream log at two periods of their lives. Correlational analyses showed that the lower the participants' self-reported levels of PWB, the more their dreams tended to contain aggressive as opposed to friendly interactions, negative emotions as opposed to positive ones, and, to lesser extent, failures and misfortunes as opposed to successes and good fortunes. Similarly, PWB was significantly related to dream content over time. These findings are consistent with the continuity hypothesis.

Abstract
Nightmares are usually defined as frightening dreams that awaken the sleeper. This study uses the waking criterion to distinguish between nightmares and bad dreams and investigated the variety and intensity of emotions reported in each form of disturbing dream. Ninety participants recorded their dreams for 4 consecutive weeks and, for each dream recalled, noted the emotions present and their intensities on a 9-point scale. Thirty-six participants reported at least one nightmare and one bad dream over the 4 weeks covered by the log, while 29 reported having had at least one bad dream but no nightmares. Nightmares were rated as being significantly (p < 0.001) more intense than bad dreams. Thirty percent of nightmares and 51% of bad dreams contained primary emotions other than fear. The findings support the claim that awakening can serve as an indirect measure of nightmare intensity and raise important implications for the operational definition of nightmares.

Abstract
The DSM-IV-TR definition of nightmares-extremely frightening dreams from which the person wakes up directly-is unnecessarily narrow. Other emotions (anger, grief) have also been reported in nightmares, and direct awakening from a bad dream seems to be unrelated to increased distress. In addition, assessment of nightmares is problematic. Polysomnographic recordings have an ameliorating effect on nightmare frequency, retrospective measurements tend to underestimate nightmare frequency, and persons with frequent nightmares may feel reluctant to fill out (daily) prospective measurements. For studying nightmares, it is necessary to distinguish idiopathic nightmares from posttraumatic nightmares, which are part of a posttraumatic stress reaction or disorder that may result from experiencing a traumatic event. Both types of nightmares have been associated with an elevated level of periodic limb movements, although only posttraumatic nightmares seem to be related to more and longer nocturnal awakenings. Nightmares have also been repeatedly associated with the general level of psychopathology, or the so-called personality factor neuroticism. Nightmare distress, the impact on daily functioning caused by nightmares, may function as a mediating variable. Several studies in the last decades have shown that nightmares can be treated with several cognitive-behavioral techniques. The cognitive-restructuring technique imagery rehearsal therapy is the treatment of choice for nightmares, although a randomized controlled trial with an attention control-group has not yet been carried out. Nightmares are more than a symptom of a larger (anxiety) syndrome and need to be viewed from a sleep medicine perspective: nightmares are a highly prevalent and separate sleep disorder that can and should receive specific treatment.

Abstract
In this article, in an attempt to integrate recent findings with existing knowledge, we provide an overview of issues related to nightmares that could be useful as a guide to clinical work. After defining what should be considered as a nightmare, we look into the relationship of nightmares with issues such as normal development and maturation, as well as culture. Issues of stress and personality are then discussed in their relation to situational and chronic nightmares. State and trait factors are further elaborated on as we explore the relationship of nightmares and psychopathology. A brief review of organic and pharmacological causes of nightmares follows before we embark on a discussion of issues that relate nightmares to psychological trauma. Some final remarks on treatment conclude our review.

Abstract
We investigated the impact of imagery rehearsal treatment (IRT) on nightmare frequency, psychological distress, and sleep quality using polysomnography (PSG). 12 chronic nightmare patients completed prospective dream logs, measures of psychological distress, and underwent PSG prior to and 8.5 weeks following a single IRT session. Post-treatment, significant reductions were observed in retrospective nightmare frequency (d = 1.06, p = .007), prospective bad dream frequency (d = 0.53, p = .03), and anxiety scores (d = 1.01, p = .004). Minimal sleep alterations were found post-IRT, and varied as a function of nightmare etiology. The results independently replicate the efficacy of IRT for alleviating disturbing dreams and psychological distress. Sleep improvement may occur later in the recovery process.

Abstract
Nightmares can be defined as very disturbing dreams, the events or emotions of which cause the dreamer to wake up. In contrast, unpleasant dreams can be defined in terms of a negative emotional rating of a dream, irrespective of whether or not the emotions or events of the dream woke the dreamer. This study addresses whether frequency of unpleasant dreams is a better index of low well-being than is frequency of nightmares. A total of 147 participants reported their nightmare frequency retrospectively and then kept a log of all dreams, including nightmares, for 2 weeks, and rated each dream for pleasantness/unpleasantness. Anxiety, depression, neuroticism, and acute stress were found to be associated with nightmare distress (ND) (the trait-like general level of distress in waking-life caused by having nightmares) and prospective frequency of unpleasant dreams, and less so with the mean emotional tone of all dreams, or retrospective or prospective nightmare frequency. Correlations between low well-being and retrospective nightmare frequency became insignificant when trait ND was controlled for, but correlations with prospective unpleasant dream frequency were maintained. The reporting of nightmares may thus be confounded and modulated by trait ND: such confounding does not occur for the reporting of unpleasant dreams in general. Thus there may be attributional components to deciding that one has been awoken by a dream, which can affect estimated nightmare frequency and its relationship with well-being. Underestimation of nightmare frequency by the retrospective questionnaire compared with logs was found to be a function of mean dream unpleasantness and ND.

Abstract
Although a potentially helpful therapeutic tool, dream interpretation or dream work is only used occasionally in most forms of psychotherapy. Despite an interest from clinicians and clients alike in using dreams within therapy, many therapists feel unprepared to attend to their clients' dreams. The main goals of this article are to make clinicians aware that integrating dreams into their clinical practice is both accessible and potentially valuable and to allow them to make an informed decision as to what role they want dream work to play in therapy. The paper begins with a brief overview of some of the more common approaches to dream work. The literature on the usefulness and effectiveness of the clinical use of dreams is then reviewed. Finally, based on the integration of the clinical and empirical literature, several guidelines for conducting dream work are presented.

Abstract
Although patients frequently experience sleep disturbances and nightmares in the first weeks after a severe burn, information is scarce on the course and prevention of this problem. Prolonged experience of nightmares in adults is one of the symptoms of posttraumatic stress disorder. The aim of this work was to determine risk factors for developing chronic nightmares after severe burns. Personality traits and coping strategies were assessed. As part of a follow-up study of patients treated at the Burn Center at Uppsala University Hospital, Uppsala, Sweden, between 1980 and 1995, the questionnaires of 166 patients (34 females, 132 males, average age 50 years, average burn size 25% TBSA, full-thickness burn size 10% TBSA, average time since burn 11.4 years) were analyzed. The effects of individual personality traits and coping strategies on the frequency of nightmares were evaluated by regression analysis. Nightmares were reported by 43% of the patients, by females more frequently than males. The frequency of nightmares was shown to be associated with the size of the full-thickness burn. The use of Avoidance or Revaluation/Adjustment scales as coping strategies and the presence of Somatic Trait Anxiety as a personality trait were associated with a higher frequency of nightmares after correction for gender. In contrast, persons seeking Emotional Support as a coping strategy reported significantly fewer nightmares. Certain personality traits and coping strategies apparently increase the risk of having nightmares after a severe burn. Helping persons at risk develop different coping strategies may be a possible means of prevention or treatment.
