Les émotions sont un aspect marquant des rêves : elles pourraient jouer un rôle dans le maintien du bien être des individus en traitant les souvenirs négatifs et en préparant aux menaces à venir. Elles surviennent surtout lors des rêves de sommeil paradoxal (SP), qui comporte une paralysie musculaire, une activité EEG rapide et des mouvements oculaires rapides (MOR). Comprendre si ce rôle de...
Dream recall frequency and lucid dream frequency showed large inter-individual differences that are partly related to personality dimensions. However, as dream research is a small field, independent studies are necessary to build a solid empirical foundation. The present online survey included 1,537 participants (1150 women, 387 men) with a mean age of 35.1 ± 15.8 years. Whereas the...
Dreams are often viewed as fascinating but relatively irrelevant mental epihenomena of the sleeping mind with questionable or no functional relevance. Despite long hours of oneiric activity, and high individual differences in dream recall, dream amnesia is one of the most robust and universal features of dreaming. In this review, we conceptualize dreaming and dream amnesia as inherent aspects...
Background: It is uncommon for dreamers to be aware of their dreaming status while being inside their own dream. Yet, it is possible to become mindful and conscious of the fact that one is dreaming. This fairly rare phenomenon is called lucid dreaming. Cognitive functions are preserved while sleeping, and in the case of trained and experienced lucid dreamers, this also permits them to manage...
Objective: Nightmares seem to predict suicidal behaviors, and the aim of this study is to explore the chronology and trajectories of alterations in dream contents before a suicidal crisis, distinguishing 3 different experiences: bad dreams, nightmares, and suicidal scenarios during dreams. Methods: This naturalistic study included individuals hospitalized between January 2021 and May 2021 in a...
Nightmare disorder (ND) is characterized by dreams with strong negative emotions occurring during rapid eye movement (REM) sleep. ND is mainly treated by imagery rehearsal therapy (IRT), where the patients are asked to change the negative story line of their nightmare to a more positive one. We here used targeted memory reactivation (TMR) during REM sleep to strengthen IRT-related memories and...
Lucid dreaming is being conscious within one’s own dream. In recent years, dream lucidity has started to attract more attention not only from the broad neuroscience field but also from applied neurology, psychiatry, sports performance science, or art therapy areas. The aim of this research is to investigate and evaluate some of the therapeutic potentials of dream lucidity. The findings propose...

Nightmares are considerably prevalent in the general population and are known to be closely associated with a variety of mental disorders. However, not much is known about the immediate antecedents and consequences of nightmares. Therefore, we used intensive longitudinal assessments to investigate the night-to-night within-person associations between nightmares on the one hand and fear of...
Nightmares are a substantial burden for sleep quality. Previous studies have shown that traumatic experiences can increase the probability of nightmares, and also waking-life distress can enhance this effect. There is evidence that the intensity of negative dream emotions is more responsible for rating a dream as a nightmare than threatening dream contents. However, there is still a lack of...

INTRODUCTION Post-traumatic stress disorder (PTSD) is a major public health problem. The most frequent complaints in this pathology are sleep disorders and trauma-related nightmares in particular. Trauma-related nightmares are characteristic of PTSD and impact its severity insofar as they are associated with more severe, longer-lasting symptoms and resistance to first-line treatments. There are...
