Everyone has a dark side, a side that not many people see. Sometimes normal people can flip and turn into monsters, triggerd by a small thing. This is connected to our shadow.
The Shadow, is a psychological term introduced by Jung. It is everything in us that is unconscious, repressed, undeveloped and denied. Dark rejected aspects of our life. We all confront our shadows in our life, that is part of self-awareness.
The shadow shows itself in many instances. For example, you might say something stupid then apologize and say I did not mean it. However, the shadow decided that it was its turn to say something. It has it say whether we find it good or not. Does an I or E type have a different shadow? that is possible. But even the most E type people have a dark side of repressed feelings.
Most of us try repressing our shadow, because we are afraid of those thoughts and worried by what can happen. We do this to get accepted, we do this as we seek being part of family, friends, society, etc.
so what is the advice here? release your shadow? I do not know, my shadow is dormant most of the time. I know this though, sooner or later, the shadow must have its say.
"Everyone carries a shadow, and the less it is embodied in the individual?s conscious life,the blacker and denser it is. At all counts, it forms an unconscious snag,thwarting our most well-meant intentions. - Carl Jung."
