The life we lead in our dreams, especially in healthy, pleasant dreams, is simpler and easier than our waking life.
We obliterate distance and transport ourselves wherever our fancy chooses; our strength is herculean; we defy the law of gravitation and rise or soar with or without wings; we brave law and custom; we abandon all modesty and make ourselves the centre of the world, which is OUR world, not any one else’s world.
The simplification of life is attained in dreams through three processes, visualization, condensation and symbolization.
The dream is always a vision. Other sensations than visual ones may be experienced in dreams but they are only secondary elements.
In other words, we may now and then hear sounds, perceive odours, etc., but the dream is based primarily on a scene which is perceived visually, not on sounds, odours, etc., now and then accompanied by a visual perception.
In fact we seldom hear sounds in our dreams, unless they are actual sounds produced in our immediate environment; the people who address us in dreams do not actually emit sounds but seem to communicate their thought to us directly without any auditory medium. Seldom do we taste or smell things in dreams.
On the other hand, we translate every stimulus reaching our senses in sleep, be it sound, taste, smell, touch, into a visual presentation. This process is to be compared to the gesticulation of primitive individuals who attempt to visualize everything they describe, indicating the length, height, bulk of objects through more or less appropriate mimic and who convey the idea of a bad odour by holding their nose, of pleasing food, by rubbing their stomach, etc.
The dramatization of every thought and every problem follows the line of least effort. And this explains the popularity of the movies, the enjoyment of which does not presuppose on the part of the audience any capacity to conceive abstract ideas.
Movie audiences are undoubtedly the least intelligent aggregations of people. They are not told that a crime has been committed, they are shown the crime while it is being committed. Captions warn them of what they are going to see, that they may not misunderstand the meaning of any scene. The movie, like our unconscious, translates every thought into a visual sensation, and when a psychological change cannot very well be visualized, for instance when the villain decides not to kill the ingenue, the fact is flashed on the screen in large type.
Pleasures of the eye are probably stronger and simpler than those vouchsafed by other sensory organs.[3] The most uninteresting parade will attract thousands of people, many more for instance, than free concerts in the open. Illustrated lectures appeal to more people than lectures without illustrations. Displays in shop windows, picturesque signs, possess a greater selling power than the best advertising copy.
