Whether it’s folklore or seeing it with their own eyes, many people think that dogs can see supernatural things, in other words they can see things that people can’t see. The evidence is that when the dog is at the door, it will bark in an empty space without people, or in an empty room, staring at a blind spot in horror, and then barking and backing away.
Others think that dogs can still communicate with their dead owners, and these people also cite some very strange examples. For example, an American author once wrote a case. In a small town in Florida, USA, a lady named Johnson raised 7 dogs and 6 cats during her lifetime. After her death, neighbors discovered that these pets would suddenly gather in one place every day, and all the animals were staring in the same direction. Afterwards, the cat would arch its back and bark, while the dog would be lying on the ground with its belly facing up, as if someone was playing with them.
The strange behavior of these animals is like Johansson is standing in one place and feeding them food. Therefore, the local people think that the ghost of Johnson may return here every day. And some studies have confirmed that dogs can behave strangely in some legendary haunted houses. So, can dogs really see ghosts?
Strong environmental perception ability
For some scientists with a positivist spirit, this view is obviously not scientific enough. Some people pointed out that just as studies have found that many people’s spiritual experiences are only caused by the interference of magnetic fields and infrasound waves, dogs may also be interfered by these environmental factors. .
Another reason is that dogs are more able to perceive small changes in the environment that some people cannot detect with the naked eye. Dogs have well-developed receptors, their sense of smell is 1,000 to 10,000 times more sensitive than humans, and their perception of audio ranges from 67 Hz to 45,000 Hz, while that of humans is 20 Hz to 20,000 Hz. Dogs can hear sounds more than 4 times farther than humans, which means that dogs can hear or smell sounds or smells that humans cannot feel.
Although dogs seem to be “nearsighted” compared to humans, their eyesight is only about three-quarters of humans, and they can’t focus on objects within 60 cm of the eyeball, so they often turn a blind eye to food that is close to them. But the dog can detect the picture that moves 70 frames per second, while the movement of the general TV picture is about 60 frames per second, which means that the dog has a special ability to detect moving targets. Because the cornea is larger, more light can enter the eyes. Dogs have better vision than humans in dimly lit environments.
These excellent sensory organs allow dogs to “see six directions and hear all directions.” So, when a dog barks for no reason, it may just notice something you haven’t noticed. Maybe it’s an unfamiliar smell, or a change in air pressure, or some shaking objects that you can’t see in your sight. Humans can generally use their brains to determine what some things appear in front of them, such as a shadow dangling by, people will rule out whether it is because a fast-moving cat has just passed the door. But dogs do not have the ability of human judgment. When their sensitive organs feel changes in air pressure or the environment, they have no way to know what these changes mean. They can only express anxiety through a series of actions such as barking, tail wagging, and salivation. , And these strange actions will appear incomprehensible to humans who are used to using language and text to communicate.
Dogs also have traumatic memories?
In addition, zoologists believe that the reason why some dogs have many strange reactions is from early traumatic memories. For example, dogs that have experienced severe weather conditions such as storms, hurricanes, or tornadoes are more sensitive to small changes in the environment, and these dogs are more likely to respond to small changes in the environment. So, if your dog barks often, it may be affected by its early experience.
Psychologists also pointed out that another reason for the prevalence of the view that dogs can be psychic is the unique mysticism tendency of human beings, which reflects that we are not firm in the view that the world is material. If a person with a scientific spirit encounters such a situation, he will try to explore the reason from a scientific point of view, but for those who believe in the existence of ghosts, they will associate it with spiritual events without thinking.
