Can animals dream like humans? Can humans dream, can other animals dream? Why do people dream?

Most reptiles don't dream; Birds dream, but most species only dream briefly; All kinds of mammals, such as cats, dogs, horses and other domestic animals, as well as elephants, mice, hedgehogs, squirrels, rats, armadillos, bats, etc., will dream, some dream more frequently, some less often; Fish, amphibians, and invertebrates do not dream. When dreaming, people have shallow breathing, rapid heartbeat, increased blood pressure, double cerebral blood volume, and some twitching of the face and limbs. At this time, the eye movement can be measured with an eye locometer, and fast waves must appear on the EEG at the same time.

Therefore, in general, "REM" plus "EEG fast waves" can be used as a marker of dreaming. In some animals using the above method, when the frog is asleep, there are only a few slow wave curves, and there is no "EEG fast wave" and "rapid eye movement" period, so it can be determined that the frog does not dream. Turtles have "rapid eye movements" and "EEG fast waves" when sleeping, but they are very short, accounting for only 2% of the sleep time.

From this, it can be determined that the turtle has very little time to dream. Cats, dogs, and monkeys all have dreams, and the dreams are longer, with monkeys being the longest, dogs being the second, and cats being the shortest. The study of animal dreaming is a matter of great interest.

Animals dream, what exactly do they dream about? There is a great deal of urgency to get to the bottom of this. However, animals can't speak and can't tell us, which is a real problem.

American scientists conducted such experiments on monkeys: a screen was set up in front of a monkey, and the same picture appeared on the screen repeatedly; Whenever this image is shown on the screen, the monkey is forced to push a lever next to him. If the monkey refuses to perform, hit it with an electric baton.

After a few days, the monkey developed a conditioned reflex: as soon as it saw the image, it took the initiative to push the lever. Later, scientists discovered that the monkey would also push the lever from time to time during sleep.

This indicates that the monkey "saw" the image in its sleep. French physiologist Pohill. Nov did an interesting experiment with cats.

He used chemical and surgical methods to block a part of the cat's brain called the pons. As a result of this, when the cat dreams about something, it acts according to the dream. After the operation, the cat suddenly raised its head in its deep sleep, looked around, and then got up again and walked around in circles, as if looking for food.

Suddenly, it raised its front paws, its ears pressed against its head, and lunged at the imaginary enemy. Nove also locked up two cats that had undergone surgery together for observation, and found that the two cats, who had been living in harmony, suddenly started fighting while falling asleep. To prove that these actions were made in his sleep, Nov deliberately made a noise by striking objects next to the cats and even placed the mice next to them.

However, the two cats were indifferent to everything that was happening around them, and they continued to attack their opponents. According to Nove, the two cats are fighting against their dream rivals. Cats can dream, but they don't dream for more than 5 minutes at a time.

Dreams are an involuntary imaginary activity that occurs during a person's sleep and is carried out unconsciously. "REM" combined with "EEG fast waves" are generally used as markers of dreaming, and scientists have measured some animals and speculated that some animals also dream. The occurrence of sleep and dreams is related to how evolved the brain is.

Sleep and dreaming only occur when the brain develops to a certain extent. So most reptiles don't dream, birds do, all kinds of mammals do.

Other animals also have dreams, such as puppies that hum for no reason when they sleep. People dream day and night, and they think too much during the day, and things are not resolved, so that they sleep and dream at night.

Animals also dream, such as cats, dogs, and other mammals.

My dog will dream when he is asleep, the performance is that he will kick his legs, feel like he wants to run, open his eyes after waking up and find that it is a dream, then relax his vigilance, continue to close his eyes and sleep, judging from its reaction, it should be a nightmare. People who have ever had a cat also know that cats can dream, they not only dream, but also talk in their dreams, when dreaming, there will be a stop of snoring, eyes rolling, the roots of the beard and hands and feet trembling slightly, and when the purr starts again, it means that the dream is over.

Animals also dream, with monkeys having the longest dreams and cats having the shortest.

REM and EEG fast waves can be used as markers of dreaming, the longer the REM and non-REM cycles, the longer the dream, the longer the dream, the cat dreams for no more than 5 minutes at a time, and the monkey dreams are more complex and longer. Animal dreams will be much simpler than human beings, their dreams will only repeat the daytime life, dogs' dreams are mostly related to smell, but some dogs with big hearts dream a little less, think more, heavy dogs will often dream, this is probably also a day of thought, night dreams.

Animals also dream, but not all animals do.

Fish, amphibians and invertebrates do not dream, and scientists have conducted similar monitoring experiments on them using electronic instruments that measure human brain waves, and found that fish, amphibians and invertebrates do not"EEG fast waves"with"Rapid eye movement"period, so they don't dream. And for other animals,"Rapid eye movement"with"EEG fast waves"The length of time is a reflection of how long the animal dreams, and the animal not only dreams, but also suffers from insomnia.

Most reptiles don't dream; Birds dream, but most species only dream briefly; All kinds of mammals, such as cats, dogs, and other domestic animals, as well as elephants, mice, hedgehogs, squirrels, rats, bats, etc., will dream, some dream more frequently, and some less often; Fish, amphibians, and invertebrates do not dream.

According to scientific research, there are many animals that also dream, because when dreaming, the surface of the brain will have some specific reactions, and some animals will also have such a reaction in their brain waves, so animals should also dream.

It is said that most reptiles do not dream, but birds do, but dreams are short-lived.

Animals also dream, and they also encounter things every day, so they will form such an effect on their heads. Then there will be a reaction.

Animals also dream, and if you have a few small animals at home, you can observe that sometimes they will chirp and kick their feet when they sleep, in short, they show a state of uneasiness.

Definitely, some scientists have tested animals to see if they can dream based on the changes in brain waves when people dream, and later found that animals also dream.

Yes, I think animals do.

Third, it can help people to provide more inspiration. Finally, there is another point that can help people provide more inspiration, because there are many things in people's imagination that can be turned from nothing into reality, so I think ** writers will write what they think in their minds in books.

Both humans and animals can dream, and when they dream, they don't necessarily have any effect. Because dreaming only means that you may be more tired during this time, the things you care about will come to your mind.

In fact, dreaming is a very normal psychological phenomenon, and it does have some benefits, such as relieving our fatigue, but often having nightmares is not good, and we need to adjust our sleeping position to reduce such situations.

Of course, dreaming makes people feel that sleep is good, as the so-called thinking during the day and dreaming at night, dreaming may also reflect the inner desire of people and animals.

If you have a pet, you will probably see some signs of a dream if you look closely at the way cats and dogs are asleep: the sleeping animal may kick its legs and feet, may wag its tail, or may bark. So, do these animals really dream like humans?

To put it simply, the answer to this question is: it is indeed very possible, but it is still uncertain.

Many mammals have similar brain structures and sleep patterns to humans, and when they are asleep, they also experience rapid eye movement (REM sleep), which is closely related to dreams in humans, so it makes sense that they can dream.

And, there are indeed some studies suggesting that animals are likely dreaming. For example, one of these classic experiments came from neuroscientist Michel Jouvet. In his experiments, he found that if certain structures in the cat's pons were disrupted, the inhibition of limb movement during sleep would be lifted.

When such a cat is asleep, it can be observed to raise its head and make various movements such as looking at objects or preparing to hunt. These movements suggest that the cat should "see" certain images in its sleep, just like humans do when they are dreaming.

And in laboratory studies of mice, scientists have also reported a phenomenon that is easily reminiscent of "thinking during the day and dreaming at night". In this study, microelectrodes were implanted to record the electrophysiological activity in the hippocampus of the brain during training during the day and at night when the rats were sleeping. During the day, the rats were trained to walk through circular tracks for food, and after that, the brain activity of the sleeping rats during the REM phase showed a pattern very similar to that during the daytime "maze walk".

It seems that the daytime mission scene will be replayed in the rats' "dreams".

If there is indeed some research evidence, why is it said that animals are not sure that they can dream? In fact, the reason is that the only accurate way to confirm the content of dreams is currently not to be used on other animals.

In neuroscience research, neither electrical signals nor MRI data can be directly and accurately correlated to dreams. If you want to know if a person is dreaming and what the content is, the only reliable way is to wake them up during REM sleep and ask them directly what they can recall. However, we can't communicate with experimental animals verbally......Therefore, at present, scientists cannot directly prove that animals actually dream like humans.

Scientists have come to the conclusion that most reptiles do not dream; Birds dream, but most species only dream briefly;

Birds dream, but most species only dream briefly;

I don't think some low-IQ animals can dream.

Yes, this one has information, dogs will run in dreams, cats will bite when they have nightmares.

Some animals can dream Scientists have concluded that most reptiles do not dream.

Of course, animals sleep and dream.

Most reptiles don't dream; Birds dream.

Animals do, but not all animals do, mammals dream.

This is generally not true, after all, thinking is relatively simple.

I guess so, I don't know.
