Delusional ideation is characteristic of psychopathology (e.g., psychosis, bipolar disorder) and is also found among the general population. Contemporary case studies have documented delusional ideation as a feature of meditation-induced psychosis, and Buddhist literature on the side effects and adverse effects of meditation also includes discussion of transient experiences that could be...

Background Psychedelic drug experiences are shaped by current-moment contextual factors, commonly categorized as internal (set) and external (setting). Potential influences of past environments, however, have received little attention. Aims To investigate how previous environmental stimuli shaped the experiences of patients receiving ketamine for treatment-resistant depression (TRD), and...

Abstract Purpose: Delusional ideation, defined as false beliefs and altered thinking, has long been attributed to anomalous/bizarre perceptual experiences and reasoning deficits. Recent studies, however, have challenged this view, suggesting instead that delusional ideation may have more of a social component to its phenomenology and underlying mechanisms. This study investigated associations...

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...

An upsurge in dream and nightmare frequency has been noted since the beginning of the COVID-19 pandemic and research shows increases in levels of stress, depression and anxiety during this time. Growing evidence suggests that dream content has a bi-directional relationship with psychopathology, and that dreams react to new, personally significant and emotional experiences. The first lockdown...

Despite a high prevalence and broad interest in flying dreams, these exceptional experiences remain infrequent. Our study aimed to (1) induce flying dreams using a custom-built virtual reality (VR) flying task, (2) examine their phenomenological correlates and (3) investigate their relations to participant state and trait factors. 137 participants underwent VR-flying followed by a morning nap....

Sleep paralysis is an experience of being temporarily unable to move or talk during the transitional periods between sleep and wakefulness: at sleep onset or upon awakening. The feeling of paralysis may be accompanied by a variety of vivid and intense sensory experiences, including mentation in visual, auditory, and tactile modalities, as well as a distinct feeling of presence. This chapter...

Les théories récentes de la conscience incarnée (embodiment) soulignent que l'esprit est un processus incarné, impliquant le cerveau, le corps et l'environnement. Plusieurs aspects de la cognition, de l’interaction sensorimotrice avec l’environnement à la pensée abstraite et métaphorique, ont été conceptualisés dans ce paradigme. Le sommeil et le rêve, cependant, ont rarement été abordés par...

Both rapid eye movement (REM) sleep dreaming and non-rapid eye movement (NREM) sleep spindles have been linked to processes of memory consolidation. However, relationships between the two phenomena have yet to be explored. In a heterogeneous sample of 53 healthy subjects who had participated in a memory consolidation protocol and who varied in their self-reported recall of dreams and...

Memory consolidation is associated with sleep physiology but the contribution of specific sleep stages remains controversial. To clarify the contribution of REM sleep, participants were administered two REM sleep-sensitive tasks to determine if associated changes occurred only in REM sleep. Twenty-two participants (7 men) were administered the Corsi Block Tapping and Tower of Hanoi tasks prior...

Isolated reports have long suggested a similarity in content and thought processes across mind wandering (MW) during waking, and dream mentation during sleep. This overlap has encouraged speculation that both "daydreaming" and dreaming may engage similar brain mechanisms. To explore this possibility, we systematically examined published first-person experiential reports of MW and dreaming and...

Study objectives: Rapid eye movement (REM) sleep, non-rapid eye movement (NREM) sleep, and sleep spindles are all implicated in the consolidation of procedural memories. The relative contributions of sleep stages and sleep spindles was previously shown to depend on individual differences in task processing. Experience with Vipassana meditation is one such individual difference that has not been...

Vipassana meditation is characterized by observing bodily sensations, developing emotional and attentional stability and promoting pro-social qualities. Whether these qualities are also reflected in dream content is not currently known. Evidence relating dream content with sleep-depending learning is mixed: some studies suggest that dreaming of a task is beneficial for improvement, while others...
