"III. Dreams
A .Dreams
To be honest, science didn´t know much about dreams for a long time. Dream-books as well as hypnosis were parts of fair entertainment from which scientists turned their faces away. Who started to treat dreams seriously was Sigmund Freud and his student Carl Gustav Jung took it to perfectness.
Dreams can be expressions of our secret wishes, our fear or stress. Subconsciousness plays an important role in what we dream about. Dreams have a close connection with our thinking and acting.
Dreams are symbolic transformations of what we feel during the sleep. In dreams the rational logic is supressed and that causes that we often meet very strange things there. Sometimes dreams are anxious and tough, another time they are bright and joyful. They are not meaningless though.

B. Kinds of dreams
We can divide dreams in fantastic and light dreams.
In fantastic dreams we don´t find any logic but we often see strange people, monsters
or special creatures, nonlogical or unimaginable storylines, we are able to walk on the
water, we visit far-away distances, we fly or anything else. These dreams, which are
also called hard dreams come up from cells that were most exhausted during the day.
When we dream the light dreams, they are often close to the real life and logic and
there we usually continue in the activity or work that we payed much attention to
during the day, or we dream about the experience which hard influenced us. Most of
the time it is troubles or problems.

C. Contents of dreams
Contents of dreams come up from 3 sources:
1) inside sources ( tiredness, pain, sickness )
2) outside sources ( different noises, feeling cold or warm )
3) psychic sources ( memories from the childhood, from previous days... )
Outside sources are most of the time impulses from the outside world which surrounds
a sleeping person. These impulses influence our perceptions and they evoke the
storyline of the dream.
Inside dreams are divided into organic, psychical impulses, subjective excitement. Most of the sources are psychic: important experiences, memories, daily fantazies, secret or open wishes, outstanding problems and so on.
First we will talk about outside sources. We can demonstrably prove them. For example when there is a storm outside, thunders can evoke a dream about us in a battle or war. When we hear a rooster-crow it sounds to us like a call for help, when we lose our blanket during the night we might dream about falling into cold water or walking around naked. It depends on each person´s individuality though. Some impulse can evoke completely something different to one man and to another one.
Dreams can also be precognitive and that means we can see a prevision which can come true in the future. "
