Our brain : The factory of emotions

Emotions and feelings could be manufactured at will.
Our brain is like a supercomputer that will execute any program as long as it doesn't clash with our principles, views and beliefs.
Actors are well-trained in that regard. They could generate fear, sadness, or intense happiness and have the same physiological responses that these emotions normally produce.
Fear is all around us, fear of the dark, fear of small spaces, fear of open spaces, fear of round vegetables, and the list goes on and on.
Some of these fears are real, and justified, most of them are not since the encounter with round peas is not life-threatening in any way.
To each one of these specific fears, there is a list of symptoms, and a memorable, sophisticated name, “arachnophobia” being one of them that we readily associate with the feared object.
The unusual way these names roll off the tongue infuses in people feelings of dread, gives life to these fears and conjures up distressing images.
Our imagination is a factory of our emotions anf feeling, it could produce dread, and it could also produce happiness and equanimity, it all depends on the nature of the raw material we provide it with, joyeful thoughts or despondent thoughts.
