Is split personality happens to everybody on this world? Or it happens only on certain people? only on lunatic?
Normal people will have different emotion, is that consider as split personality? Just imagine this. When one try to do something bad, lets say, cut class, will he/she struggle between do and don't? If he/she does, is that means he/she has a split personality of God and Evil?
When a person scared of something or someone, is that his/her another personality? In our normal life, it is not considered as it. But why? What is the difference?
What is split personality? From Wikipedia, its medical term is Dissociative Identity Disorder (DID), or Multiple Personality Disorder. It describes a mental illness in which a single person displays multiple distinct identities or personalities, each with its own pattern of perceiving and interacting with the environment.
Why human emotion considered as "emotion" and not split personality? Like what I asked, when a person scared of something or someone, he might think of hiding at a corner or try to avoid it from happening. What if the "thing" that he scared has came too close and forced him to think of some other solution? Will he do something else? Chinese idiom says "Forcing the tiger to jump over a wall" (逼虎跳墻) If we can force someone to do something he won't do at normal time, is that means that his second identity has take over the control at that particular moment?
Wikipedia says that DID needs to associate with memory loss that goes beyond normal forgetfulness. We all heard this before: human brain will tends to block memory that brings extreme pain. There are cases of victims of trauma has no conscious memory of the trauma event. Is that means they has DID?
I think this is a topic we can argue for ages. Just to bring it out for discussion. You can leave comment if you have any answer or idea about it.
