Do people hallucinate and animals dream and hallucinate?

Scientists have come to the conclusion after research: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.

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 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, Noff deliberately made a noise by hitting objects next to the cats, and even placed Lao 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.

Animals also hallucinate, and animals also have brains, but they have not evolved to the level of humans.

Hallucinations are caused by a disorder of brain function, which manifests itself as an abnormality in mental activity, and hallucinates it as if it were a dream.

Personally, I think animals can also dream, but their dreams should be relatively short.

It is true that there are some animals that also have dreams and also hallucinate.

Yes, any animal has rest and brain disturbances that will be affected.

It should also be possible, because it is also living things that are also affected by the environment.

Animals certainly do, too, because there are many similarities between animals and humans.

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.

Hallucinations generally include visual hallucinations, auditory hallucinations, color hallucinations, olfactory hallucinations ......and so onThe most common of these are visual and auditory hallucinations!

Hallucinations are in a specific state! (Generally divided into two types: one is a high degree of mental concentration, and the other is a semi-awake state) mental activity that makes the brain give wrong instructions!

When the mind is highly concentrated, the frequency of information transmission is beyond the range of what the brain can tolerate in a normal state! Overload your brain with wrong instructions! When semi-awake, the brain reduces its ability to receive and analyze information!

The same error instruction will be issued!When these incorrect instructions are sent to the corresponding functional area, hallucinations are generated! For example, when the brain sends wrong instructions to the optic nerve, visual hallucinations occur!

Answer: Hello, normal people will hallucinate in two special situations. 1.In stressful situations, because high levels of stress can affect emotional instability, they can make their brain fragments disappear instantly, or hallucinations appear.

It's not like someone who is sick, has a high fever, and will hallucinate after fatigue.

2.Hallucinations can also occur under fear and anticipation fatigue, and when a person has a fear of the unknown, auditory hallucinations, visual hallucinations. There is even a fragment of anticipation, I am quietly waiting for someone to come, or anxiously waiting for someone to come, and suddenly I hear a knock on the door, then in fact no one is coming, at this time it has a close relationship with the heart, this is a situation of longing and expectation, hallucinations.

Fear creates panic and hallucinations.
