In reality, we humans can't fly like birds without tools, so why can we dream that we can fly in our dreams?
Some psychologists believe that people who dream of flying show that they are young and energetic, thinking about flying and pursuing their own ideals, so they will fly in their dreams; Others say that people dream of flying because they are growing up; Others say that flying like a bird is an idea that only children have, so flying in a dream is a sign of childlike innocence. ...
These statements seem reasonable, but they are not reliable, because flying is not a dream only for children or young people. People of any age may dream about flying, and middle-aged and elderly people may dream about flying, so dreaming about flying has nothing to do with people's age.
There is also the so-called dream interpretation master who said that when people dream that they are flying, it means that they will have a successful career, because it means that they will be promoted, good luck will come, and their career will be promoted step by step. Undoubtedly, this is far-fetched or superstitious, which can be said to be unreasonable.
What's the reason? To be precise, it is actually a phenomenon caused by people's sleeping posture. You are most likely to fly in your dreams when you sleep in a posture where you can hardly feel the existence of gravity.
People usually lie in bed when they sleep. If they lie flat on the bed with their head resting on a low pillow, their arms at their sides or straight, and their legs stretched horizontally, they will sleep comfortably, or sleep on the bed with their limbs spread out. At this time, you are likely to dream of flying.
Why is this happening? It is precisely because in this sleeping position, the body can hardly feel the existence of gravity, so what will happen if the human body loses gravity? Of course it will float in the air.
When we usually walk, almost all parts of the body will feel the existence of gravity. Because the gravity of the earth will act on the human body, people always rely on the nervous system to maintain the balance of the body. This work is mainly done by cerebellum. During most of the day, the cerebellum and other nervous systems must always participate in maintaining the balance of the human body. Only when lying flat on the bed, all parts of the body are in close contact with the bedding. Gravity has been completely transformed into the bed, and the cerebellum and other nervous systems can hardly feel the existence of the body's center of gravity, which means that the cranial nerve system will not produce gravity induction at this time, or can't find where gravity is. If you fall asleep and relax completely at this time, you may have a flying dream.
So the main reason why people dream is that the sleeping position of the body makes the brain nervous system think that the body is in weightlessness. In weightlessness, people can of course fly at will. Just like the astronauts on the space station, they can't feel the gravity of the earth, and their activities are similar to flying. So when they stay in the space station for a long time, most of them will fly when they sleep and dream.
In fact, it's not just a dream of flying, sometimes people dream of swimming. Even people who can't swim dream of swimming freely in the water. In fact, the same is true, that is, when people sleep, the cerebellum and other nervous systems can't feel the existence of gravity, just like floating in water, so they dream of swimming.
However, when dreaming of swimming, it is usually that the quilt blanket covered on the body is thin or even uncovered, which makes the body feel very cold, so I dream of swimming in the water, because in people's subconscious, the water is usually cold. People often dream of water or rain when they are cold or feel cold when they are asleep.
