I've been fairly involved in a VR Game for many months now, and I have met a good portion of people who claim they have a split personality disorder. I know a bit on how it works, but I feel like some of them are lying about it because they'll just, switch avatars and act different. Say they have a different name, claim to not remember me at all, just keep doing that. Sometimes they'll just change for a long time (weeks?) and a friend said they're submissive to one of their other personalities. 

I don't want to say they're lying, because it is a real disorder but I feel like it's more a detachment from reality and in the game than it is a personality disorder.
