An internal resistance always accompanies a process of decision-making that can be seen as a symptom of a split personality. This duality is not always strict. It can’t change the main characteristics or influence a way of life. To a certain point, a human can control this sensation. However, in the case of a dissociative identity disorder, a person may lose individuality, get fragmented and feel as several, independent personalities. When the alternate identity becomes dominant and episodic memory gradually recovers, the sense that you are not alone follows. The retrospection (sudden and unexpected return of memories) brings the fear of identification along with the personal “I”.
