Scientific point of view
Every day in life is full of events that are remembered by the brain and cause certain reactions. During sleep, at rest, is only the human body. The brain during this period repeats and reinforces all the information that can become the so-called scenario of the dream.
In the dream the person can see the events of the day, the recent situation or the distant past.

The dream from the point of view of psychology

Dreams are not remembered, if the person is awake in deep sleep. This usually occurs in cases where sleep is interrupted by a loud sound, trying to Wake up a man or with too long a dream.
Fatigue can also cause lack of dreams. In people who sleep little and work a lot, the brain is oversaturated with information. During sleep, images flashed in our minds so quickly that in memory almost never deposited.
