Thus, it is not unexpected that transportation also plays a significant role in dreams. In a long series (N = 11,463 dreams) of one dreamer (single-case study) about 16% of the dreams included some form of transportation. The dreamer who is driving cars very rarely, dreamed more often about being a co-driver than a driver – in contrast to persons who drive a car regularly, supporting the continuity hypothesis of dreaming. On the other hand, several dreams were “creative”, i.e., don’t reflect any actual waking-life experiences of the dreamer, for example, traveling in a spaceship or submarine. Car trouble dreams were frequent (40% of the car driving dreams) even though the dreamer never experienced car trouble in waking life, e.g., malfunctioning brakes. This supports the idea of Patricia Garfield that this dream type is metaphorically linked to feelings of not being in control in waking life. Very interesting topics for future research would be studying the relationship of “creative” dreams, i.e., dreams that did not reflect directly the actual waking-life experience of the dreamer, and his or her waking life and the possible metaphoric link between car trouble dreams and waking-life stress.","PeriodicalId":38642,"journal":{"name":"International Journal of Dream Research","volume":"1 1","pages":"56-61"},"PeriodicalIF":0.0,"publicationDate":"2020-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48547318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nor does conceiving of dreams as a by-product of the random nature of neuronal processes appear to permit useful information to be obtained from them. In order to verify this point, this study aimed to test the possibility of obtaining valid and reliable information from dream content based on the attributes of the Dream Self; that is, the character of the actual dreamer who appears in the dream. Information was collected from 235 dreams of 169 people with a mean age of 29.8 years. This was achieved with a self-report questionnaire evaluating 186 attributes of the Dream Self. Attributes related to anxiety upon awakening were subjected to exploratory factor analysis. There were 99 attributes related to anxiety upon awakening and with 44 of them it was possible to find a solution with 3 easily interpretable factors. These factors had alpha coefficients of between .78 and .90 and were related to anxiety upon awakening. The results obtained did not support the idea that dreams are a random phenomenon. Furthermore, it was possible to evaluate dreams through 3 dimensions of the Dream Self: Emotional-Social Unease, Threat-Avoidance and Strangeness-Confusion. It was possible to partially explain these dimensions by means of the continuity hypothesis of dreaming and Revonsuo’s (2000) evolutionary theory.","PeriodicalId":38642,"journal":{"name":"International Journal of Dream Research","volume":"1 1","pages":"29-39"},"PeriodicalIF":0.0,"publicationDate":"2020-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44499088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While anxiety disorders are a rather widely investigated group of mental disorders, study of dreams and dream content of people suffering from anxiety and anxiety disorders is relatively scant. Therefore, the present review serves to summarize and give a comprehensive and contemporary overview of the existing studies and research on the topic of relationship between dreams and anxiety and anxiety disorders. In addition, it might help to emphasize the necessity of broader and deeper research of this problem and further research and studies on the topic. It contains a survey of interrelations between dream content and dream disturbances and trait and state anxiety in non-clinical and clinical populations, between dream content and dream disturbances and anxiety disorders in clinical populations, and the relationships between nightmare distress and anxiety. It also provides a glimpse on the relationships between dreams and comorbid anxiety and depression and the influence of anxiety on dream recall frequency. In sum, the results show that due to the relatively low number of studies which deal with this topic and their relative inconsistency, the problem of these interrelations and connections is not extensively or comprehensively investigated and developed up to this day, while the findings on such relationships and associations still remain heterogeneous and diverse to a certain extent. Therefore, further deeper and more profound research and investigation of this particular topic is required and seems necessary.","PeriodicalId":38642,"journal":{"name":"International Journal of Dream Research","volume":"1 1","pages":"1-16"},"PeriodicalIF":0.0,"publicationDate":"2020-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49516482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

About 90% of the participants reported some benefit of lucid dreams on their waking life including mental and physical health. This benefit was related to higher lucid dream frequency, trait mindfulness, and spirituality. These prom-ising results should encourage researchers to develop a manualized lucid dream therapy and test its effect on physical and mental health in a randomized waiting-list pre-post design.

This provides a unique opportunity for dream research, as lucid dreamers can send real-time signals from sleep to the external world. Historically, such sleep-to-wake communication from a lucid dream is executed via left-right eye movements, which places hard limitations on information transfer. Recent advances in biomedical equipment — specifically brain-computer interfaces — have resulted in headsets that use neural recordings to translate mental imagery into computer commands. In light of evidence suggesting that dreamed and imagined actions recruit similar neural resources, I considered the possibility that the same mental commands that are collected and translated from waking imagery could be similarly performed and detected from within a lucid dream. In this exploratory study with proof-of-concept intent, three participants were asked to use an Emotiv EPOC+ headset and companion software to map a mental motor command (pushing a block) with a resulting computer action (graphic of block moving forward). After waking training, participants attempted to induce a lucid dream while wearing the headset, and upon lucidity perform the same mental command. In two participants, subjectively reported lucid dream task completion was corroborated with video footage of the resulting computer graphic. These preliminary results suggest that a wake-trained brain-computer interface can be controlled from sleep and offer important directions for future dream communication and research.","PeriodicalId":38642,"journal":{"name":"International Journal of Dream Research","volume":" ","pages":"62-69"},"PeriodicalIF":0.0,"publicationDate":"2019-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46530787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on neuroscience and cognitive research, a new model for nightmare generation was created, the AMPHAC/AND neurocognitive model, that suggests nightmares involve an internal fear-memory extinction process facilitating recovery from trauma. The model further identifies repeating nightmares as an impairment of the psychological healing process because they prevent the generation of fear-extinction memories. The two types of repeating nightmares (those that recreate the trauma [i.e., replicative nightmares] and those that repeat but are not recreations of trauma [i.e., recurrent nightmares]) were evaluated to determine if they are significantly related to PTSD symptom severity and nightmare distress, which is implicated by the model in impairing novel, fear-extinction memory generating nightmares. 78 participants were recruited and provided responses to questions evaluating the frequency of repeating nightmares, PTSD symptom severity, nightmare distress, and their experiences of IPV. Analyses of these responses generated the findings that both types of repeating nightmares are significantly correlated with PTSD symptom severity and nightmare distress, and there is a significant negative correlation between the length of time since the last repeating nightmare and PTSD symptom severity.","PeriodicalId":38642,"journal":{"name":"International Journal of Dream Research","volume":"1 1","pages":"14-22"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46708973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
