This is a term that would be referred to as an identity disorder. Everyone has one and it stems from having difficulty distinguishing thoughts, memories and feelings experienced as belonging uniquely to the self from those ascribed by others or arising from external impressions.
Every personality has an “individuality complex,” which means they have difficulty differentiating their thoughts, memories, feelings with those of other people or simply attributing them externally. Psychologist Carl Jung discusses this in his book Psychiatrie und Neurologie where he states that each individual builds up a new individuality through the projection of these archetypes based upon their experiences or fantasies; but also we should not forget that every person has a deep unconscious which contains dark wishes and primal impulses. Our individuality complex is formed by our instinctual roots and unconscious, the things that have always been with us.
It’s rather difficult to explain in words but when you start looking into it or researching it further then it will be quite clear when you see for yourself what an individuality complex actually is. I don’t like to use labels on people so I won’t be sticking one on myself, but this is just something that will stick out more to each individual.
It’s not actually a disorder though it is seen as an identity disorder by some psychologists. It’s quite similar really to narcissistic personality disorder or antisocial behavior which is associated with narcissism and sociopathy. Although individuality complex is not an actual disorder it can affect your life and the way others perceive you.
For instance, someone may believe that they possess magical powers or their perception of reality is distorted to such a degree which causes them to become delusional (think of David Icke). Another example would be megalomania; this is when someone has an inflated sense of self-importance. They believe they are superior to others and have power over them, or that other people cannot do the same things as they can do. This may also involve delusions where you begin to think that you’re more powerful than God himself which ultimately leads down to having hallucinations (seeing things in reality which don’t exist).
