Dogs have been close human companions for millennia and one would expect-according to the continuity hypothesis of dreaming-that dogs are also quite common in dreams. Previous studies showed that the percentages of dreams that include dogs range from about 1.5% to 5%, but studies relating waking-life experiences with dogs with dreams about dogs have not been carried out. In total, 1695 persons...
Anecdotal evidence that lucid dreaming might contribute to mental and physical health has been widely reported in the literature. Empirical research, though, is scarce. A brief questionnaire eliciting self-perceived benefits of lucid dreaming on mental and physical health had been completed by 386 participants who had lucid dream experiences. About 90% of the participants reported some benefit...
Sci-fi has had a lot to say about dreaming over the years: film director Christopher Nolan, fiction writer Ursula Le Guin, anime director Satoshi Kon, and many others have explored the weird and wonderful world of dreams. Inception begins with the premise that it’s possible to enter someone’s dream and extract information from their mind. In the first experiment of its kind, a research team led...

We used crowdsourcing (CS) to examine how COVID-19 lockdown affects the content of dreams and nightmares. The CS took place on the sixth week of the lockdown. Over the course of 1 week, 4,275 respondents (mean age 43, SD = 14 years) assessed their sleep, and 811 reported their dream content. Overall, respondents slept substantially more (54.2%) but reported an average increase of awakenings...
Dreams are experiences that occur during sleep, while we are disconnected from the environment. Thanks to recent progress in neuroimaging techniques, it is now becoming possible to relate dream features to specific patterns of brain activity. Some conditions occurring in patients with neurological disorders, such as lucid dreams and parasomnias, not only have diagnostic value, but also offer a...

Experience replay (ER) improves the data efficiency of off-policy reinforcement learning (RL) algorithms by allowing an agent to store and reuse its past experiences in a replay buffer. While many techniques have been proposed to enhance ER by biasing how experiences are sampled from the buffer, thus far they have not considered strategies for refreshing experiences inside the buffer. In this...
Propensity to have nightmares has been theorised in terms of diathesis-stress models, with this propensity being seen as negative or even pathological. In contrast, a recent model proposes that nightmare propensity is due to Differential Susceptibility to stimuli, where high susceptibility can be beneficial in positive environments but detrimental in negative environments. This susceptibility...
Lucid dreaming is a phenomenon that can be classified as altered state of consciousness. In the last years the scientific interest for it has grown exponentially. To understand how the research on this topic evolved during the time, bibliometric and network analyses were performed. The focus of the analysis was on: 1) papers; 2) authors; 3) countries and 4) collaborations. Scopus database was...
