15 interesting things that happen to you in a dream
Sleep (Latin somnus) is a natural physiological process of being in a state with a minimum level of cerebral activity and a reduced response to the surrounding world, inherent in mammals, birds, fish and some other animals, including insects (eg, fruit fly).
In addition, the word "dream" refers to the sequence of images (formed during the so-called "fast sleep" phase) that a person can remember (see also the dream). Physiologically, ordinary sleep differs from other similar states - anabiosis (so-called "hibernation" in animals), hypnotic sleep, coma, fainting, lethargic sleep.
Most people sleep about a third of their lives. But, strangely enough, we know very little about the occupation, which we spend so much time on. There are separate clinics that help people with sleep disorders, and a lot of medical research focused on the incredible things that happen when we fall asleep. About fifteen of them we will tell today.
1. You are excited
You may think that you are excited in a dream because of your fantasies, but this phenomenon has a more scientific explanation. During a fast sleep phase, your brain is so active that it requires more oxygen. As a result, the blood flow in the body increases. And you know perfectly well what leads to a rush of blood to the lower part of the trunk. In a dream, both men and women are excited. In rare cases, some people even have sex in a dream or have other sexual activity - a phenomenon known as sexomnia.
2. It seems to you that your head exploded
You probably did not even hear about the syndrome of the exploding head, but this is the strangest thing that can happen to us in a dream. People who experience this crazy phenomenon, hear deafening fictitious sounds (for example, a bomb explosion) right before falling asleep or waking up. Scary! In fact, people who suffer from this syndrome often have high levels of stress and fear. It is believed that instead of "turning off" before going to sleep, the brain cells responsible for the sound are triggered simultaneously, which creates an explosion of energy that the brain takes for a loud sound. Fortunately, this syndrome is not very widespread.
3. Or just send a message right away
A new phenomenon, which appeared due to abundant SMS-correspondence. Yes, a nightmare, when you accidentally send a message to the wrong person, is a reality for some people when they go to bed. It is a growing phenomenon among teenagers and those who are constantly in touch during the day. To protect yourself from this disaster, just remove the phone from the bedroom, or at least away from the bed.
4. You can also talk
About 5 percent of people talk in a dream, but this harmless disorder is more common in children than in adults, and more often among men than women. Most people do not remember what they talked about in a dream, but many of us from our own experience know that these conversations are very strange!
5. You can even walk
Perhaps you either go to sleep yourself, or you know someone who does it - it's quite a common phenomenon. Usually it manifests early in the night, when the body falls into a half-conscious state, just before the fast sleep phase. Scientists are still trying to figure out why some people walk in a dream, while others do not. Of course, walking in a dream can be dangerous, so that, contrary to popular opinion, a person in this state can not just be awakened, but even necessary.
6. Do you excrete growth hormone
When we were children, we were always driven to bed early, so that we slept through the night - and for many reasons. One of them is for us to grow and develop. When we sleep, the secretion of growth hormone in the pituitary gland reaches its peak. This hormone, which is obviously responsible for the growth of muscles and bones. It is also important for the regulation of metabolism and stimulation of collagen, which gives the skin youthfulness
7. It seems to you that you are falling
A common, but rather strange thing, that 70% of people are experiencing - you experience a feeling of falling right before you fall asleep or wake up. Also known as hypnagogic twitching, this sleep disturbance can be caused by the remaining energy, which is manifested by random movements. There is also a version that this is the result of brain confusion - it seems to him that you are falling, as all muscles relax, and he makes them tense to "catch" you.
8. Your dreams are repeated again and again
Have you ever dreamed the same dream time after time? Do not worry, you are not alone. Many people experience repetitive dreams, and, perhaps, it's time to pay attention to them. It is believed that recurring dreams symbolize unresolved problems that we encounter during wakefulness. Although sleep does not always specifically indicate what is happening in your life, it most likely includes meaningful topics. For example, when you are experiencing because of a failure in the
9. You let the gases out
When you sleep, your body relaxes, and with it muscles. Unfortunately, this also applies to the anal sphincter. Because of this, gases are easier to exit. This fact can embarrass you when you next decide to go to bed with your second half, but do not worry - fortunately, we do not smell in a dream!
10. Your sense of smell is dulled
You can wake up and feel the divine smell of delicious breakfast and coffee, but these wonderful smells can not wake you. Because we do not smell in a dream. The reason is not known exactly, although this may be a consequence of the loss of contextual stimuli. Therefore, it is so important to get a fire alarm. Even if the smell is very sharp, you can not feel it if you sleep. Although some people have smells, they are actually created by the brain.
11. You solve problems
Have you ever gone to bed with an unsolved problem in your head, but woke up already with an answer? This, oddly enough, is not uncommon, and explains the phrase "the morning is wiser than evening." Although you may think that your brain rests while you sleep, in fact it focuses on solving problems that did not give you rest in the afternoon. Researchers believe that sleep opens access to a network of associations in your head, which allows you to solve the problem (this is called "activating a wide network").
12. You are paralyzed
During the fast sleep phase, the muscles in your hands are temporarily paralyzed. This, in fact, is very useful. Can you imagine that you dreamed that you were beating someone while you were lying next to your second half? Although this temporary paralysis occurs with everyone, some people have a condition called "sleep paralysis" - in which case paralysis lasts several minutes after awakening. Sleep paralysis is not dangerous, but, of course, quite scary for those who experience it.
13. Do you lose weight?
A dream is, to some extent, a short fast. You do not absorb anything in a dream, but at the same time you lose water, sweating and exhaling the moist air. This leads to a small weight loss, especially if you manage to snatch seven or eight hours of sleep. In fact, in a dream a person burns an average of about 60 calories per hour. This is not much, but ultimately leads to the result, if you do not forget about healthy eating and sports.
14. Your eyes are moving fast
If you've ever watched a sleeper, you've probably noticed how his eyeballs move under closed eyelids. Pretty scary, right? Eyes quickly move from side to side during the phase of rapid sleep (BDG-phase, "rapid eye movements"), and this is logical. This is the phase when you dream, so that your eyes just adjust to changing the scene or image in a dream. This is not the same as looking around in a dream - in this case it is a question of brain activity during a change in the concept of sleep. This explains why even blind people experience BDG in a dream!
15. You delete useless information
The amount of information that the brain absorbs every day is uncountable. As soon as you leave on the street in the morning, the brain immediately begins to absorb the colors around you, the voices of passers-by and a bunch of other information that you do not need to remember. If you remembered all this, your brain would be overloaded, and it would be hard for you to remember the really necessary things. Fortunately, the brain sorts all this information while you sleep, and erases unnecessary.
