Converging evidence suggests that dreaming is influenced by the consolidation of memory during sleep. Following encoding, recently formed memory traces are gradually stabilized and reorganized into a more permanent form of long-term storage. Sleep provides an optimal neurophysiological state to facilitate this process, allowing memory networks to be repeatedly reactivated in the absence of new...
Dreaming is an important state of consciousness that complements the awake state. Self-awareness, as well as the ability to recognize other people, are essential characteristics of everyday life. The recognition of Self and others is based on, among others, autobiographical and episodic memory, and emotional, and evaluative systems, or perceptual cues. The goal of the paper is to answer a...
This article explores transcendental experiences during meditation practice and the integration of transcendental experiences and the unfolding of higher states of consciousness with waking, dreaming, and sleeping. The subject/object relationship during transcendental experiences is characterized by the absence of time, space, and body sense--the framework that gives meaning to waking...
We normally assess another individual's level of consciousness based on her or his ability to interact with the surrounding environment and communicate. Usually, if we observe purposeful behavior, appropriate responses to sensory inputs, and, above all, appropriate answers to questions, we can be reasonably sure that the person is conscious. However, we know that consciousness can be entirely...
Llewellyn's proposal that rapid eye movement (REM) dreaming reflects elaborative encoding mediated by the hippocampus ("seahorse") offers an interesting perspective for understanding hallucinations accompanying sleep paralysis (SP; "night-mare"). SP arises from anomalous intrusion of REM processes into waking consciousness, including threat-detection systems mediated by the amygdala ("almond")....
A voluminous amount of research on the multi-faceted complex process of meditation is now available. Meditation [Dhyan], an ancient Indian art and science of healing, has an immense potential to liberate the mankind from the Stress Associated Diseases [SADs] which, today, are addressed as Noninfectious Chronic Diseases [NCDs]. But unfortunately the Conclusion from the currently available...
Can ancient art of memory (AAOM) principles explain the function of dreaming? The analysis of self-experience in dreams suggests that the answer is no: The phenomenal dream self lacks certain dimensions that are crucial for the efficacy of AAOM in wakefulness. However, the comparison between dreams and AAOM may be fruitful by suggesting new perspectives for the study of lucid dreaming as well...
Are dreams subjective experiences during sleep? Is it like something to dream, or is it only like something to remember dreams after awakening? Specifically, can dream reports be trusted to reveal what it is like to dream, and should they count as evidence for saying that dreams are conscious experiences at all? The goal of this article is to investigate the relationship between dreaming, dream...
All mammals show the physiological correlates of waking, dreaming and deep sleep. Many contemplative traditions propose a fourth state of consciousness, “silent consciousness,” defined as consciousness without reportable contents. For example, the Mandukya Upanishad, one of the root texts of Vedanta philosophy, explicitly claims a fourth state of “consciousness without content.” (Sharma, 1997)...
Even when we are ostensibly doing "nothing"-as during states of rest, sleep, and reverie-the brain continues to process information. In resting wakefulness, the mind generates thoughts, plans for the future, and imagines fictitious scenarios. In sleep, when the demands of sensory input are reduced, our experience turns to the thoughts and images we call "dreaming." Far from being a meaningless...
