The central nervous system (CNS) consists of the brain and the spinal cord, immersed in the cerebrospinal fluid (CSF). Weighing about 3 pounds (1.4 kilograms), the brain consists of three main structures: the cerebrum, the cerebellum and the brainstem. Cerebrum - divided into two hemispheres (left and right), each consists of four lobes (frontal, parietal, occipital and temporal). The outer layer of the brain is known as the cerebral cortex or the ‘grey matter’.
This page describes a number of lucid dream induction techniques. It is recommended that you be able to recall at least one dream per night in order to maximize the effectiveness of these methods. [ edit ] Preliminary Knowledge Certain elements are common to many of the lucidity-inducing techniques discussed later in this chapter.
A lucid dream is any dream in which one is aware that one is dreaming. The term was coined by the Dutch psychiatrist and writer Frederik (Willem) van Eeden (1860–1932). [ 1 ] In a lucid dream, the dreamer can exert some degree of control over their participation within the dream or be able to manipulate their imaginary experiences in the dream environment. [ 2 ] Lucid dreams can be realistic and vivid. [ 3 ] It is shown that there are higher amounts of beta-1 frequency band (13–19 Hz) experienced by lucid dreamers, hence there is an increased amount of activity in the parietal lobes making lucid dreaming a conscious process. [ 4 ] Lucid dreaming has been researched scientifically, and its existence is well established. [ 5 ] [ 6 ] [ edit ] Scientific history
The Forer effect (also called the Barnum effect after P. T. Barnum 's observation that "we've got something for everyone") is the observation that individuals will give high accuracy ratings to descriptions of their personality that supposedly are tailored specifically for them, but are in fact vague and general enough to apply to a wide range of people. This effect can provide a partial explanation for the widespread acceptance of some beliefs and practices, such as religion , astrology , fortune telling , graphology , and some types of personality test . A related and more general phenomenon is that of subjective validation . [ 1 ] Subjective validation occurs when two unrelated or even random events are perceived to be related because a belief, expectancy, or hypothesis demands a relationship. Thus people seek a correspondence between their perception of their personality and the contents of a horoscope.
