An unusual phenomenon when your pet suddenly jumps and watches into an empty angle, as if there is something or someone, it can be impressive. This phenomenon is also observed in children, and they may respond to some invisible entities.
The reason why animals can see "ghosts" related to their ability to perceive ultraviolet light, which goes unnoticed to the human eye without special adaptations. Ultraviolet light covers the range from red to purple, and some animals, such as monkeys, pandas, dogs and cats, can perceive the world around this spectrum.
The study of London biologists has shown that some animals can see ultraviolet radiation, which allows them to respond to things that go unnoticed for humans. For example, it may be traces of potential prey or pollen on the flowers that bees see.
This leads to the assumption that pets, such as cats and dogs, can see ultraviolet reflections that allows them to respond to something that remains invisible to the human eye. This can explain situations where animals begin to behave strangely and watch something invisible to us.
It is also worth noting that children can see "ghosts" for other reasons, such as lack of adult attention. If the child creates an imaginary friend, it may indicate that they lack the attention of adults. In this case, it is important to pay attention to the child, spend more time together and provide his or her emotional needs.
The child's mind is also open to the new and unknown, and this can lead to the fact that children perceive reality differently than adults. Therefore, it is important to listen to the child, understand her outlook and create a safe environment to express her imagination.
