To investigate the changes in cortical neural responses induced by external inputs during phasic rapid eye movement (p-REM) sleep. Single-pulse electrical stimulation (SPES) was directly applied to the human cortex during REM sleep through subdural electrodes, in seven patients who underwent invasive presurgical evaluation for intractable partial epilepsy. SPES was applied to parts of the...
Past research has suggested that reflective awareness in dreams, as a broader concept for understanding the phenomenon of lucid dreaming, can be further differentiated into a five-factor model (i.e., lucid mindfulness, dual perspectives, depersonalization, intra-dream self-reflection, and willed appearances) (Lee, 2010; Lee & Kuiken, 2015). Past research has also indicated that two kinds of...
All empirical science is based on systematic observations and measurements. Consciousness itself, especially its qualitative features, is invisible to physical research instruments. The challenge for consciousness science is to find methods by which to observe and measure subjective conscious experiences accurately and systematically. Many data-collection methods in psychology are indirect...
Abstract Sosa (Proc Addresses Am Philos Assoc 79(2): 7–18, 2005) argues that we should reject the orthodox conception of dreaming—the view that dream states and waking states are “intrinsically alike, though different in their causes and effects” (2005: p. 7). The alternative he proposes is that “to dream is to imagine” (2005: p. 7). According to this imagination model of dreaming, our dreamt...
Our understanding of the effects of meditations developing existential insight is very limited. This chapter provides an in-depth examination of this type of meditation, starting with an overview of insight practice categories and conceptualizations. Neuroscientific evidence relevant to existential insight practices is discussed in four categories: attentional foundations of existential...
Dreaming is a common human experience investigated from multiple perspectives over the centuries. Recently, this phenomenon has stimulated scientific interest, becoming a peculiar context to study memory processes and consciousness (1).

Telepathic effects could be investigated during the dreaming phase of the sleep cycle. The use of the Rapid Eye Movement (REM) technique freed the investigator from the uncertainty of relying upon spontaneous dream recall. The telepathy hypothesis was generally introduced on the basis of the following criteria: elements in the dream of the patient revealed a striking similarity to events...

The Inventory Déjà Vu Experiences Assessment (IDEA) is the only screening instrument proposed to evaluate Déjà vu (DV) experience. Here we intended to validate the Italian version of IDEA (I-IDEA) and at the same time to investigate the incidence and subjective qualities of DV phenomenon in Italian healthy adult individuals on basis of an Italian multicentre observational study. In this study...
In March, 1974, a 46-item questionnaire was mailed to a randomly selected sample consisting of 300 students from the University of Virginia and 700 other adult residents of Charlottesville and surrounding suburbs. Items requested respondents to report the incidence and detailed characteristics of various psychic and psi-related experiences. Information concerning attitudes and the personal...
Chronotype refers to individual differences in sleep timing and in preferences for a given time of day while sleep duration refers to the hours of sleep. Here, we assessed chronotype, sleep duration, and nightmare frequency in relation to the Big Five personality factors. Overall, 2,492 persons (1,437 women, 1,055 men) completed the online survey between March 23, 2015, and April 8, 2015. The...
