personally, i don't know someone who has that DID thing or multiple personality. it's like ...it's so hard to detect if a certain person has it, i mean one in every hundred people or even one in a thousand.
but one noticeable tv series that features as such is Heroes... yeah, the lady there (i forgot the name) that portrays like a psycho-killer. There she has a child and a husband, all of them have powers or so-called mutancy. Her real personality is a loving mother to her child but when the personality sinks in her, she become evil and kill people.
i hope that make sense yo
