Identifying fear-related nightmares in children is particularly challenging, as young children often struggle to articulate their experiences or recall dream content. These nightmares, however, can severely disrupt sleep, hinder academic performance, and heighten psychological vulnerability, underscoring the need foraccurate and early prediction for effective intervention. This study explores...
Several measures eliciting nightmare frequency have been developed over the years. Most of the measures show sufficient reliability, but some studies are based on the four-point item of the Pittsburgh Sleep Quality Index (PSQI) measuring bad dream frequency – even though reliability data for this item have not been published. The present study included a sample of N = 277 participants...
REM sleep behavior disorder, often an early marker of α-synucleinopathies, is characterized by the loss of REM-related muscle atonia and the occurrence of dream enactment behaviors. Dream reports in REM sleep behavior disorder are frequently described as more vivid, violent, and negative than typical dreams. However, evidence for this remains inconsistent, likely due to methodological...
Background: Lucid dreaming (LD) is a state in which individuals become aware that they are dreaming and can exert control over their dream content. Equanimity (EQU) refers to a state of psychological stability, where one remains calm, balanced, and non-reactive in the face of stress or adversity. While LD has been linked to emotional regulation, its predictive relationship with EQU remains...
Abstract Jean-Paul Sartre develops a phenomenological account of dreaming in his early work on the imaginary. Providing a brief but rich analysis, he emphasizes the active and imaginative nature of consciousness during dreaming and distinguished it sharply from perception. This paper revisits Sartre’s dream theory in light of the neuroscientific and philosophical framework of Predictive...
Why should we be interested in the relationship between dreaming and memory?Dreaming and Memory: Philosophical Issues sets out to explore this issue, offering rigorous and thought-provoking investigations into how these two phenomena might illuminate one another.Bringing together a range of philosophical perspectives, the volume navigates the blurred boundaries of these two cognitive...
Nightmares are associated with psychopathological symptoms. This study aimed to investigate the prevalence of nightmares and heterogeneity of nightmare distress and examine the association between nightmares and mental health problems with a broader sample of Chinese college students. A total of 5,824 college students were assessed in our study. Participants completed a self-reported...

Epilepsy impacts cognition during wakefulness. As epileptic activity is present and even augmented during sleep, epilepsy could also influence sleep-related cognitive processes. However, whether epilepsy modulates sleep-related experiences like dreaming remains poorly known. Here, we prospectively investigated the characteristics and determinants of dreaming in patients with epilepsy....
Abstract: This article explores ways to reconcile paradoxes of embodiment in Śaṅkara’s doctrine of liberation-while-living ( jīvanmukti ) by exploring its parallels with lucid dreaming. I engage in lucid dreaming as a thought experiment in which a lucid dreamer could feasibly reflect on dream experience through an Advaita Vedāntic philosophical lens. If approached this way, lucid dreaming...
Abstract Patients undergoing general anesthesia are often assumed to be unconscious. However, it is known that conscious experiences in the form of dreams occur even in unresponsive states induced by anesthetics. Here, we recorded resting state electroencephalography (EEG) as well as EEG combined with TMS perturbations in 20 healthy participants during propofol sedation. Participants were...
