ISBN ] [ Source: The Lucidity Institute ] Chapter 8: Function And Meaning Why do we have dreams and what do they mean? These questions have for centuries been the subject of a debate that has recently become the center of a heated controversy.
In one camp we have a number of prominent scientists who argue that we dream for physiological reasons alone and that dreams are essentially mental nonsense devoid of psychological meaning: This camp takes its credo from the Talmudic aphorism that "an uninterpreted dream is like an unopened letter.
Its proponents argue that dreams may have both physiological and psychological determinants, and therefore can be either meaningful or meaningless, varying greatly in terms of psychological significance.
This middle position is where I find myself most comfortable. I agree with Sir Richard Burton that "Truth is the shattered mirror strown in myriad bits; while each believes his little bit the whole to own. Although people have argued for many centuries over whether dreams represent the addle-minded children of an idle brain, the heaven-sent embodiment of wisdom, or something in between, we will confine our discussion to "scientific" theories of dreaming at least as modern as the 20th century.
So then, let us start with Dr. The Interpretation Of Dreams Revisited If we are to understand Freud's view of the dream, we need to consider his concept of the dreamer's brain. We know today that the nervous system contains two types of nerve cells excitatory and inhibitory.
Both types discharge and transmit electrochemical impulses to other neurons. Both do this spontaneously, without any kind of outside stimuli, as well as when they themselves receive excitatory impulses from other cells. However, one critical difference between these two types of neurons is that one type, called "excitatory" transmits impulses to other neurons which causes increased nervous activity or "excitation" in them.
The other type of neurons is called "inhibitory," because they send messages to other neurons that cause decreased activity or "inhibition. Generally, the inhibitory neurons play a more important role in the higher functions of the brain.
Before developing his theory of dreams, Dr. Freud had intensively studied neurobiology. But, in his time, only the process of excitation had been discovered; the process of inhibition was not yet known.
Based on the assumption of a completely excitatory nervous system, Freud reasoned that nervous, or in his terms, "psychic," energy could therefore only be discharged by means of motor action. This meant that once you got a notion in your head, it was doomed to run around in there forever until you finally decided to do something about it.
Or, alternatively, until it found a way to trick you into unconsciously expressing it in some unintended action like the famous "Freudian slip.
However, given the state of knowledge of his time, Freud's view of the unconscious mind as a cauldron seething with socially unacceptable impulses and desires appears perfectly reasonable; and likewise, from it his theory of dreaming can readily be seen to follow. Let us imagine what might have happened if you were somehow able to ask the master himself why you had a particular dream.
Freud, we may speculate, might have answered something like this: In the first place, we may be sure that something happened to you a day or two before the dream and that this "day residue"--as we call it--stirred up one of the many repressed wishes that you try to keep closeted away in your unconscious.
But, when you drifted off to sleep with no other wish in your conscious mind than to sleep, you withdrew your attention from the external world, setting the stage for your day residue and associated unconscious wish to step forward, demanding satisfaction.
All this requires the cooperation of the chief executive of your conscious mind, the ego. But because your pair of suppliants were not, let us say, 'dressed in a socially acceptable manner,' they were at first denied admission to your conscious mind.Fulfillment by Amazon (FBA) is a service we offer sellers that lets them store their products in Amazon's fulfillment centers, and we directly pack, ship, and provide customer service for these products.
Failure rate is the frequency with which an engineered system or component fails, expressed in failures per unit of time. It is often denoted by the Greek letter λ (lambda) and is highly used in reliability engineering.. The failure rate of a system usually depends on time, with the rate varying over the life cycle of the system.

2. Raising a number n to a power p is the same as multiplying n by itself p times.
Write a function called “Power” that takes a double value for n and an int value for p, and returns the result as a double value.
Here, the ^ denotes the power function, but it is not computed by calling the 1st Pow(x, n) function; instead it is implemented within the 3rd function, concurrently with the .
