Why do we have dreams

Creation is one of the most mysterious, mysterious and inexplicable phenomena that occur to a person. And they occur in the subconscious when we sleep, and our brain continues to work, but in another reality, in another space, drawing its unusual and mysterious images that we can remember or forget, trying to understand what they mean.

The question why we see dreams and what does this or that night action of the brain mean is very relevant and controversial, as many scientists are trying to find answers, to find ways to unravel and interpret dreams. This is only partially possible, because each case has its own unforeseen and probably even unsolved features and nuances.

Dream Stages

All dreams can be divided into two types – fast and slow dreams. If a dream is slow, it means that it is ordinary, normal, when a person is in a state of night rest. And fast dreams are accompanied by dreams. When we fall asleep, the phase of slow dreams is activated. Here we can distinguish 4 stages, and each of them has certain processes:

  • The first stage – a person falls asleep, sails away into the world of dreams and otherworldly reality, even fluttering of the body at this moment is observed. Muscle activity decreases, eyes move slowly.
  • The second stage is a shallow sleep, when there is a slowdown of heart rate, muscle relaxation, a slight decrease in body temperature.
  • The third and fourth stage – the body rest physically until the end of the night, until the full morning awakening.

If a person has not had a deep sleep, he will stand in a dead and tired state, when he feels the tension and lack of physical rest. All muscles will receive the necessary blood flow to maintain their activity, as well as will be released growth hormone.

When all the stages have already come, it is time for a quick sleep with dreams. Here you can find the answer why a person dreams. This is important for normal brain activity, for the order of all incoming information.

According to American scientists, during the research of the sleeping person’s nervous system, it was possible to establish high impulse activity, and this gap is seven times greater than the state of normal vigor of a person. As scientists say, this happens so that the brain can memorize and record all the past events.

The total sleep period includes the stages of slow sleep and fast sleep, which merge into one cycle lasting 90 minutes. In one night a person can see about 4-6 cycles. You will be able to sleep better if the waking moment coincides with the end of the cycle.
