This paper introduces a novel approach to lucid dream communication, leveraging electrooculographical signals for real-time, natural language messaging within dreams. Beyond traditional horizontal eye movement techniques, our methodology incorporates vertical eye movements, enhancing the expressive range of communication. Recognizing the potential for lucid dream communication in diverse...

The boundaries between waking and sleeping-when falling asleep (hypnagogic) or waking up (hypnopompic)-can be challenging for our ability to monitor and interpret reality. Without proper understanding, bizarre but relatively normal hypnagogic/hypnopompic experiences can be misinterpreted as psychotic hallucinations (occurring, by definition, in the fully awake state), potentially leading to...

Out-of body experiences (OBEs) are characterized by the subjective experience of being located outside the physical body. Evidence supports that OBEs triggered by electrical stimulation and epileptic seizures are associated with disrupted brain activity in a distributed network centred at the temporo-parietal junction and the resulting multisensory disruption of body representation. However,...

We introduce Dreamento (Dream engineering toolbox), an open-source Python package for dream engineering using sleep electroencephalography (EEG) wearables. Dreamento main functions are (1) recording, real-time monitoring, analysis, and sensory stimulation, and (2) offline post-processing of the resulting data, both in a graphical user interface. In real-time, Dreamento is capable of (1) data...

Objective When metacognition arises during rapid eye movement (REM) sleep, people experience lucid dreaming (LD). Studies on this phenomenon face different obstacles. For example, its standard verification protocol requires at least three types of sensors. We hypothesized that preagreed frontalis movements (PAFMs), as a sign of lucidity, could be seen on electroencephalography (EEG) during REM...

Lucid dreaming, a rare state in which the dreamer realizes that he or she is dreaming, has captured the interest of scholars and sparked extensive research. This article explores the historical trajectory of lucid dreaming research, tracing its roots to the early writings of Frederick van Eeden and highlighting the key scientific contributions of Stephen LaBerge. Through a rigorous methodology,...

Dreaming is a complex phenomenon that occurs during sleep, involving various conscious dream experiences. Lucid dreams (LDs) involve heightened awareness within the dream environment, while out-of-body experiences (OBEs) involve the sensation of being outside one's physical body. OBEs occur during sleep paralysis (SP), where voluntary movements are inhibited during sleep/wake transitions while...

Night-time is a period of great significance for many people who report paranormal experiences. However, there is limited understanding of the associations between sleep variables and seemingly paranormal experiences and/or beliefs. The aim of this review is to improve our understanding of these associations while unifying a currently fragmented literature-base into a structured, practical...

The article examines the phenomenon of lucid dreaming. The author assumes that lucid dreamers share the experiences typical of meditation practice and lucid dreaming is certainly more than becoming ‘awake’ in a dream state. Most lucid dreamers experience in lucid dreams more intense sense of presence, stillness and peace, joy, compassion and love. it is worthwhile mentioning that lucid dreaming...

Nightmares can be defined as "an unpleasant dream with anxiety and oppression". They represent a symptom possibly leading to serious psychiatric and physical consequences. It occurs to 2% to 8% of the general population. Lucid dreaming therapy (LDT) is an interesting upcoming psychotherapy for the treatment of nightmares. The aim of this study was to evaluate the efficacy of LDT in the...

Lucid dreaming is a dream in which one is aware that they are dreaming while dreaming as well as being able to influence the dream. It is utilized in scientific research to explore dreaming, in clinical context to treat nightmares, and in private settings to have fun, solve problems, and to train various skills. In this paper, based on an interview with a lucid dreamer, a fascinating, yet...

Sleep is such a complex and dynamic process and dream that it still is a scientific enigma. Over more than a century of research has established a wide range of dream-relevant theories, whereas, no one has yet reached an accurate conclusion about the function and meaning of dreams. So, in this project, I desire to review the relationship between sleep and dream and illustrate what is the...

Zusammenfassung Das luzide Träumen ist ein einzigartiges Phänomen, bei dem sich eine Person während des Schlafs bewusst ist, dass sie träumt, und dadurch häufig ihre Handlungen während des Traums bewusst steuern kann. Dieser Artikel beleuchtet kritisch die methodischen Herausforderungen bei der Erforschung des luziden Träumens und bietet Strategien zu deren Bewältigung unter Berücksichtigung...

AbstractThis study aimed to investigate the efficacy of using hypnotic enhancement of auditory suggestion to induce lucid dreams in inexperienced individuals. Lucid dreaming, a state in which the dreamer becomes aware of their dream state, provides opportunities for personal exploration, sports, and clinical applications. However, the rarity of lucid dreams poses a challenge to scientific...

People typically become aware that a dream was “just a dream” only after awakening. Alternatively, people can become aware that they are dreaming during the dream. These lucid dreams are thought to involve increased prefrontal cortex activity relative to non-lucid dreams, and they are associated with volitional control over dream content. Lucid dreams could be valuable for many purposes, such...

Standard treatments for nightmares focus on waking activities, with consequences for subsequent sleep. An alternative strategy may be to provide people with a novel way to learn to end a nightmare by waking up. People typically think of sleep as a state that they cannot control, but there are exceptions to this rule. For example, the ability to select dream content in a lucid dream might allow...

Recent studies have begun to understand sleep not only as a whole-brain process but also as a complex local phenomenon controlled by specific neurotransmitters that act in different neural networks, which is called "local sleep". Moreover, the basic states of human consciousness-wakefulness, sleep onset (N1), light sleep (N2), deep sleep (N3), and rapid eye movement (REM) sleep-can concurrently...

Lucid dreams are defined as dreams in which the dreamers are aware of the fact that they are dreaming as dreams continue. It has been ~12 years since the last review of the efficiency of lucid dream induction techniques was conducted. Hence, the present study aimed to review the lucid dream induction techniques published in the past decade. The second aim was to propose a modified...

Sleep paralysis and lucid dreams are two states of consciousness that are connected to REM sleep but are defined by higher awareness in contrast to regular REM sleep. Despite these similarities, the two states differ widely in their emotional tone and their perceived controllability. This review aims to summarize the current research containing sleep paralysis and lucid dreams. However, given...
