Importance of Dreams
Psychologists distinguish two categories of sleep: superficial sleep and deep sleep. The unconscious always participates on dreams even if the person is having a deep sleep. The images perceived on deep sleep do not always reach the conscious; the images that we get to remember when we wake up correspond to superficial sleep.
There is people that as soon as they lean on bed, they fall to sleep. When it happens dreams tend to be scarce, because it looks to be that a person that falls to sleep immediately, they fall into a deep sleep.
The most of the sleepers pass through a series of images that are very well known because they antedate to the dream that arises from the deep, for a few moments a sensation of sleepiness is felt by the person that is submerged in this state, during which many images mixed with feelings and sensations left by daily activities are experienced and seen.
These images are not annoying for the sleeper as long as the sleeper do not try to fix them in a conscious way, or else, he or she will be disturbed by the lack of sleep.
Sleep and Dreaming deploy very important functions. The clearest images that we have when we wake up correspond to the last dreams we had a few moments before recovering conscience. People which have very active lives, they will tend to have very intense dreams. In a similar way, a person that has weak thoughts will tend to have dreams in short supply.
