Sleep in human life is a basic and unconditional need. In a dream, the average person spends a third of his life, that is, about 25 years. The duration of a night's rest is approximately 7-8 hours, but there are people who need 4-5 hours of sleep to fully recover and maintain their working capacity. But science still cannot explain the nature of dreams, it is only known that this is most likely a projection of our thoughts, feelings and experiences. Let's look at some interesting facts about a person’s dream.
Today, a person’s dream is usually divided into five phases, which can be repeated several times during the night.
The first phase is falling asleep. At this time, a person experiences a nap, slowly sinking into sleep. Half-asleep dreams, ideas for overcoming life's problems are possible.
The second phase is a shallow or light sleep. Muscle tone decreases, heart rate slows down, body temperature decreases.
The third and fourth phases are collectively called "slow sleep". At this time, a person is immersed in a calm, deep sleep, there is a rest and restoration of body forces.
The fifth phase of sleep is considered "fast." It is at this moment that the sleeping person can observe the rapid movements of the eyeballs. During this period, the breathing and rhythm of the heart become uneven and it is now that a person is able to see dreams.
In the process of normal full sleep, a person goes through all phases. The first phase - the transition from wakefulness to falling into sleep - the shortest, it lasts 5-10 minutes. Other phases last from 20 to 30 minutes.
From what phase of sleep a person wakes up, his health also depends. So, the rise in the fast phase is accompanied by weakness, a feeling of lack of sleep, apathy. Therefore, daytime rest should not exceed 40-60 minutes.
Scientists during the experiments were able to establish that, if a person’s dream has mainly blue and green tones, then his life is stable, measured, and nothing bad happens in it. People whose dreams are painted in shades of red are most likely to have a high temperature or some kind of disease. Black and all dark colors indicate nervous tension, overwork and, possibly, an imminent emotional breakdown.
Emotions during sleep
It has been proven that most dreams leave negative emotions rather than positive ones. The most commonly felt dream feeling is anxiety. As a result, people who are least affected by stress, are mentally and emotionally stable, rarely remember their dreams. But a suspicious and restless person, most likely, will continue to experience the feelings experienced at night for a long time.
Furnishings and People
Interesting facts about dreams relate to both the places where they occur and the characters. So, only 20% of dreams include real people and places that the sleeper is well known. The rest is a figment of fantasy, a unique picture peculiar to a particular dream and person. Some people are able to see what is happening in a dream as if from the outside, being not a participant, but an observer of events. This phenomenon is called "lucid dreaming" and is a big mystery to scientists.
Many people have often heard that there is a prophetic dream and dreams. Interesting facts about this phenomenon can be found in the specialized literature. However, such a phenomenon does not yet have an evidence base. It is believed that a single disturbing sleep can be easily ignored. But if an unpleasant dream is repeated several times, has a negative meaning, awakens feelings in a person, then it is worth considering. Perhaps this is how the brain sends warning signals to which a person simply does not pay attention during daytime wakefulness.
"What do you dream about ..."
Scientists have also noticed the following interesting facts about dreams: at least 70% of men see men in their dreams, and women equally among both sexes. Heavy smokers who abandon a bad habit see the most vivid dreams, even more colorful than people who have never smoked.
A person's sleep is accompanied by snoring only during the slow phase, however, during snoring people do not see dreams.
Dreams are also influenced by external factors. So, if a person falls asleep in a cold room, most likely, he will feel the cold in his sleep, perhaps the effect of sleep will unfold at the North Pole. During thirst, a person may dream about how he takes a glass of water and cannot drink it, as a result of which he wakes up and really realizes in real life that he is thirsty.
A dream in reality
There are proven facts about a person’s dream in reality. In order to experience a similar state, you must do the following. After a long hard day, lie down on the sofa. It is better to lie on your back, stretch your arms along the body, close your eyes. Next, you should be stationary and try not to fall asleep, you can think about something or remember the past day. After some time (usually no more than half an hour), you will feel heaviness in your chest, perhaps you will hear sounds. This is called sleep paralysis. If you open your eyes at this moment, you can see hallucinations, but the body will not be able to move, since it is already sleeping. This is a waking dream. If you close your eyes, you can already fall asleep for real.
Dreams are only for intellectuals
A team of scientists from the United States of America has been studying sleep and dreaming for several years. Interesting facts were discovered in the course of these studies. It turns out that only smart people can see dreams. This conclusion was made on the basis of a survey of more than two thousand people. Most of them claimed that they did not remember their dreams at all and were unlikely to see them at all. However, some people who passed a series of intellectual tests said that, on the contrary, they remember well part of their dreams. Further polls showed that the more mentally developed a person is, the more vivid and colorful dreams he sees.
These interesting facts about a person ’s sleep can be explained as follows: it is known that during the night's rest, the information received during the day is ordered. Accordingly, the more busy an individual is during the day, the more problems he solves and the more he thinks, the more information he receives. So, during sleep, the brain works on its "processing". And vice versa, the less active the brain during the day, the less information it receives, which means that it rests at night.
What about animals?
No less interesting facts about dreams can be found in representatives of the animal world. For example, in dolphins, half of the brain remains active during sleep. This is necessary in order to stay alert all the time and monitor the attack of predators.
Sea otters hold on to each other's paws even during sleep, so as not to move away.
Snails can sleep for about three years in a row.
70% of their lives are spent on cats sleep.
So, sleep is the most ordinary and at the same time one of the most mysterious processes that occur with the human body. Interesting facts about dreams open up more and more every year, but scientists can not always find an explanation for them. And while the best minds of the whole world are struggling to solve these processes, it remains for us to remember that without sleep a person can live only 11 days, and a daily full 8-hour night rest restores the physical and mental strength of the body, replenishes energy resources and makes it possible to live long and full life.
