The person with the Disorder of Depersonalization and Desrealización you experience feelings of strangeness with respect to himself or herself (depersonalization), and feelings of strangeness with everything that is not your person (desrealización).
With respect to itself means your body, your mind, or your self, your self, and your personality. The experience of strangeness can occur in one of these elements, or more than one, or all. The affected person may suffer from these experiences one time in your life for a moment, or all your life, permanently. Between these two extremes, there is a whole range or spectrum.
Each depersonalised lives to this evil in their own way. There are those who do not feel their own existence, there are those who feel like ghosts, there are those who feel as if they were drawings.
The desrealización is feeling strange everything external to the self. And accompanies depersonalization. There are those who feel that nothing I perceive is real, that everything what you are dreaming, that everything is drawn, or who are trapped in a dimension ghost.
