Humans are more afraid of staying in dark places than other creatures.
Every human being has different degrees of mental illness, and "Nyctophobia" is one of them.
In ancient times, human beings have associated darkness with danger. After nightfall, humans without night vision will hide themselves for safety reasons, such as staying in caves. Later, after knowing how to use fire to illuminate and drive away wild animals, the range of nocturnal activities was improved.
Even though human development is getting more and more advanced, the awareness of fear of darkness has been engraved into "DNA (Deoxyribonucleic acid, deoxyribonucleic acid)".
Even in daily life, turning off the lights to sleep and going home in the dark have become a habit. Once triggered by certain situations, the fear of darkness in the bones will awaken.
For example, in the event of a sudden power outage, watching a horror movie, or hearing a ghost story that someone has just told.
That hairy emotion will arise spontaneously.
The main cause of this is the brain's excessive speculation about what may or will happen in a dark environment.
Irony is...
"Darkness" - the most extravagant for humans of my generation who cannot be directly exposed to the sun.
Although you can still see the sunlight through the protective cover, for your own safety, staying in the dark is the foundation of survival.
Looking back at the past sci-fi films, there are pictures that describe the disparity between the rich and the poor in the future. The rich live in high-rise buildings, and the poor live underground.
The reality is...
After experiencing changes in the world war, nuclear pollution, environmental climate, etc., the former mansion with green mountains and rivers is a thing of the past. Today's rich people live in deep and safe "Bunkers". Homes that are closer to the ground are less valuable. The poorer people are more forced to live where they can see the sun.140Please respect copyright.ＰＥＮＡＮＡHG2FiWV7ko
