Why do we see dreams?

As you know, we sleep about one-third of his life, that is, more than twenty years. So many beautiful and useful things you can do during this time! But do we regret that, instead, lying like logs in their beds? Yes, almost never! Because about 5 years of those 20, we see dreams. And there will agree, sometimes events occur much more interesting than in real life. And what do we know about dreams? And nothing, rubbish, dream book and read in women's magazines. And this is bad, because the state in which we spend five years of his life, deserves more. By the way, to be precise, the concept of "dream" means precisely the process, state, and the "dream" - actually what we see at night (and not only at night). But let's not quibble over the terms. As we see, and why we do not remember dreams? Dreams see everything. Since this is unlikely anyone will argue - though a couple of dreams in a lifetime can recall each. Much more surprising - we see them every night, but still not one but five pieces. Certainly not all agree, and in vain. In fact, we just do not remember them. It does not depend on memory, but the attitude toward dreams, or rather to the fact that they show us. If a person believes their nonsense, then his dreams with the onset of the morning, most likely, delicately hiding somewhere in the depths of the subconscious. Many working and physically tire people usually sleep, "as dead" and their dreams, too scarcely remember. Dreams are the same to us every night, without asking permission and without regard to our attitude, because it is the same physiological process as everyone else. From school biology lessons should all be aware that sleep is the slow and fast, these phases during the night succeed each other. Slow dream - without dreams. REM sleep brings dreams (pardon the tautology). In the phase of REM sleep, people can be a funny sight - often breathe rapidly move the eyes, sometimes even moving, turning over and talk. If these moments man ever wake up, he earns mental disorder! Why are dreams? Of course, dreams come to us for a reason. First, dreams and REM sleep are necessary for our organism. If the dream consisted of only one slow phase, then we could dive into it too deeply. REM sleep - as a student at the lecture, which pushes the side neighbor, so that he finally fell asleep. Dreams protect our sleep. The brain perceives the external and internal exposure and include them in the story of a dream. Therefore, instead of waking up from the heat, wind, cold, you may find yourself in a virtual Sahara, on the deck of a ship or naked in the street. Also, REM sleep is necessary for brain development. Newborn, it takes 60-80% of sleep and gradually decreases to 20%. A dream of primitive man in general was almost the entire surface. If not for that, we probably would have died out many thousands of years ago. But the most curious is that our dreams are not only useful to us physically, but also help to solve all life's problems. In the essay part of dreams and the subconscious, whose voice in ordinary life we hardly hear. As you know, the roots of almost all the problems are there. In the dream, the subconscious mind is behaving like a child, ran away from their parents, that is the way he wants. And we dream behave in many respects more natural than in life, and our problems are presented in a more explicit form. Of course, if you threw favorite people, his dream did not return. But at least you can dream that you are together, or conversely, that you no longer love him and will not suffer - and thus, during sleep is quiet and peaceful. Besides, you know that if you share with someone of his misfortune, to speak, it will be a little less. Dreams - is still better than a friend or girlfriend. And in general, thank dreams need not only for the fact that they help to deal with reality, but for the fact that often have no relationship to. First, it is the nightmares that make it easier and easier to relate to real life, not a nightmare, and secondly, it's a dream in which we are doing and see something never done before and not seen (but have heard or read) - other people, things, country ... Well, how else we could try a lot of incredible sensations and impressions?
