OneirologyIn the field of psychology, the subfield of oneirology (; from Ancient Greek (oneiron)'dream' and ()'the study of') is the scientific study of dreams. Research seeks correlations between dreaming and knowledge about the functions of the brain, as well as an understanding of how the brain works during dreaming with respect to memory formation and mental disorders.
SleepNaturally recurring resting state of mind and bodySleeping Girl, Domenico Fetti, c. 1615Sleep is a state of reduced mental and physical activity in which consciousness is altered and certain sensory activity is inhibited.

DreamworkDreamwork is the exploration of the images and emotions that a dream presents and evokes. It differs from classical dream interpretation in that it does not attempt to establish a unique meaning for the dream. In this way the dream remains "alive" whereas if it has been assigned a specific meaning, it is "finished" (i.e., over and done with).
Dream interpretationDream interpretation is the process of assigning meaning to dreams. In many ancient societies, such as those of Egypt and Greece, dreaming was considered a supernatural communication or a means of divine intervention, whose message could be interpreted by people with these associated spiritual powers. In the modern era, various schools of psychology and neurobiology have offered theories about the meaning and purpose of dreams.
ImageAn image or picture is a visual representation. An image can be two-dimensional, such as a drawing, painting, or photograph, or three-dimensional, such as a carving or sculpture. Images may be displayed through other media, including a projection on a surface, activation of electronic signals, or digital displays; they can also be reproduced through mechanical means, such as photography, printmaking, or photocopying.
MindThe mind is that which thinks, feels, perceives, imagines, remembers, and wills. It covers the totality of mental phenomena, including both conscious processes, through which an individual is aware of external and internal circumstances, and unconscious processes, which can influence an individual without intention or awareness. The mind plays a central role in most aspects of human life, but its exact nature is disputed.
Recorded historyRecorded history or written history describes historical events recorded in written form or other documented communication that are subsequently evaluated by historians using the historical method. For broader world history, recorded history begins with the accounts of the ancient world around the 4th millennium BCE, and it coincides with the invention of writing.
IdeaAn idea (from the Greek word: ἰδέα (idea), meaning 'a form, or a pattern') is the result of thought. Although the word is used in common usage, in philosophy, ideas can also be mental representational images of some object. Many philosophers have considered ideas to be a fundamental ontologicalcategory of being. The capacity to create and understand the meaning of ideas is considered to be an essential and defining feature of human beings.
