Can animals dream? Through research, scientists have found that dreams are not the patent of human beings

This paper takes part in the series essay competition of “great science” of Recordunkown.

Human beings are advanced animals and intelligent life. The reason why human beings are different from other animals and become intelligent life is that human beings have an extremely intelligent and developed brain. The most mysterious thing in the human brain is consciousness, and one of the products of consciousness has puzzled scientists all the time, that is dream.

I believe many friends often have the experience of dreaming, some dreams are even very real, we can not feel that it is false in the dream, we will think that it is a real world. Only when we wake up, we realize that it was just a dream. So some people put forward a conjecture that dreams may be real, just something happened in another parallel world.

If dreams are real, does it mean that dreams are human’s patent? Other animals don’t dream? However, scientists have proved through a large number of experiments that animals can also dream, and dreaming is not the patent of human beings. Generally speaking, animals with a high degree of brain development will dream. In nature, mammals are relatively advanced, and they can basically dream like humans. Moreover, fierce predators are more likely to dream.

So what does an animal dream look like? Sometimes, when animals sleep, their legs shake and their beards shake. In fact, this time shows that they are dreaming. I believe that many friends like to keep cats. This is a kind of sleeping animal. In fact, humans also love to sleep. On average, one third of the time is spent in sleep every day.

So how do scientists determine that animals are dreaming? In fact, this is mainly related to the relationship between dreams and the brain. According to the research on human dreams by scientists, we are in an active state when we dream, and sometimes our activity is no less than that when we work in the daytime.

If we don’t dream, then the brain activity detected by the instrument is relatively weak, which is in deep sleep. But if there is a dream, then brain activity will be activated, become more excited. At this time, it can be detected by the instrument. Of course, without this instrument, we can also determine whether a person is dreaming. That is, open your eyelids to see if your eyes are rolling. If they are rolling, it means that you are dreaming.

Scientists call your eye rolling sleep “rapid eye movement sleep”, when your body can’t move. During REM sleep, your brain is very active, just as it is when you are awake, but you are not thinking, you are dreaming. So animals naturally have this kind of external performance when they dream.

Scientists have found that almost all mammals and birds have REM sleep. However, cold-blooded animals do not seem to have REM sleep. Does that mean that mammals and birds can dream, but cold-blooded animals can’t? There is no definite answer to this.

The reason why scientists like to use mice in experiments is that mice are similar to human beings in many ways. Research shows that mice, like human beings, have complex dreams and repeat what has happened in dreams. The researchers asked mice to perform specific tasks in a maze and found that this produced specific patterns of brain activity. When the mouse falls asleep, this special brain pattern reappears in the mouse’s brain, indicating that the mouse is dreaming and still walking in the maze.

A research report on Grey headed wenniao shows that they are singing in their dreams by analyzing the excitability of their brain neurons during sleep. Therefore, it is reasonable that dreams are the reappearance of reality. Many dreams are related to your real life experience. Whether it’s human or animal, things and experiences that don’t exist in real life will not appear in dreams.

It can be seen that dreams are not likely to be real existence, it is not a manifestation of brain consciousness activity, it is a kind of illusory existence. So what’s the use of dreaming? It’s been bothering scientists for a long time. Some people think that dreaming is useless, but some people put forward the opposite opinion. They think that dreaming may be very important for the brain.

Scientists have studied brain activity in sleeping animals. They cut off part of the brain when the animal is dreaming. This part of the brain allows the animals to stay still while they sleep. When this part of the brain doesn’t work, the animals start to make a lot of actions, as if they are acting out dreams. This may indicate that the animal is indeed dreaming, and it is a dream of “movement”.

In another study, scientists monitored brain activity in singing birds, and then, while the birds were asleep, they looked at brain activity. The scientists found that the brain activity was almost the same in both cases.

Dream is not useless, it may have a very important role for animals or humans. Some scientists have proved that dreaming can exercise the thinking ability of the brain and make the connection between cerebral cortex enter a more reasonable stage.

Dream also has a very good effect on people’s mental health, some patients with chronic depression, through the computer to adjust the brain wave sleep therapy, that is to say, let them enter the appropriate dream, the condition has improved to varying degrees.

It can be seen that dreaming is actually a kind of self-regulation of the human body, and an appropriate amount of dreaming has many benefits to the body. Of course, if you dream too much is not a good thing, it will also do some harm to your body. Therefore, keeping a short period of dream experience every day is a positive and healthy performance. But if you dream for a long time, you have to consider whether there is something wrong with your body. You need to find a doctor for treatment. Generally speaking, people with a weak body are prone to dream for a long time.

Of course, what is a dream? Although most scientists believe that dreams are just a kind of conscious activity in the cerebral cortex, there are some special dreams that are difficult for modern science to explain. For example, some people predict what will happen in the future through dreams, and things really happen. It’s hard for us to explain this kind of dream. Therefore, dream may not be as simple as we think. There may be more unknown mysteries waiting for us to solve.
