It appears from his dense marginal annotations that the Renaissance mathematician, imperial propagandist and occult philosopher John Dee, in the late 1550s, had with apparent interest read the In Librum Aristotelis de memoria et recordatione commentarij of Claudius Campensis. This work — in the name of refuting the ‘impious and wicked’ opinions of Aristotle who ‘linked all the faculties of the...
This study aimed to explore relationships between personality type variables and dream structure variables. In the questionnaire experiment (N=410), we investigated associations between different personality variables in the Myers-Briggs Type Indicator questionnaire (MBTI) and various aspects of dreams in the Mannheim Dream questionnaire (MADRE). The MBTI has four dimensions. In the...
The scope of human consciousness includes states departing from what most of us experience as ordinary wakefulness. These altered states of consciousness constitute a prime opportunity to study how global changes in brain activity relate to different varieties of subjective experience. We consider the problem of explaining how global signatures of altered consciousness arise from the interplay...
Dream enactment behavior commonly occurs on occasion in normal children and adults. Disruptive and frequent dream enactment behavior may come to the attention of the clinician either as the primary reason for consultation or as a prominent characteristic of a patient with other sleep disorders. Questioning patients with chronic neurologic and psychiatric disorders may also reveal previously...
Information processing during sleep is active, ongoing and accessible to engineering. Protocols such as targeted memory reactivation use sensory stimuli during sleep to reactivate memories and demonstrate subsequent, specific enhancement of their consolidation. These protocols rely on physiological, as opposed to phenomenological, evidence of their reactivation. While dream content can predict...
The reliable induction of lucid dreams is a challenge in lucid dream research. In a previous study by our research group we were able to induce in about 50% of the participants a lucid dream in a single sleep laboratory night by combining a wake-up-back-to-bed sleep protocol and a mnemonic technique. In the present study, we extended our previous procedure by additional presentation of an odor...
Mike Jay has written widely on the history of science and medicine, and particularly on the discovery of psychoactive drugs during the 18th and 19th centuries. His books on the subject include Emperors of Dreams: drugs in the nineteenth century (2000, revised edition 2011) and most recently High Society: mind-altering drugs in history and culture (2010), which accompanied the exhibition he...
Dreams in which the dreamer is aware of the dream state (lucid dreams, LD) are difficult to induce in naïve subjects in-laboratory. Recently, Stumbrys and Erlacher (2014) used a combination of existing induction techniques together with a self-developed experiment protocol and achieved comparatively high LD induction rates. In this study, we simplified their methodology slightly and repeated...
Lucid dreaming is a unique phenomenon with potential applications for therapeutic interventions. Few studies have investigated the effects of lucidity on an individual's waking mood, which could have valuable implications for improving psychological wellbeing. The current experiment aims to investigate whether the experience of lucidity enhances positive waking mood, and whether lucidity is...
Beginning in the fall of 1969, I went through a number of experiences v/hich I can only term "extraordinary". These are notes taken shortly after the first incident: A state of hyperalertness . Occurred with one other person. It was experienced as an immersion into a fantastic flow of energy and a manner of perceiving which made the "meanings" of all perceptions secondary to the direct...
