There's a word for multiple personalities in your head. That's called Dissasociative Disorder. I don't consider plotting between friends about characters or muses to be particularly harmful else 99.9 percent of the RP Cliques or RP communities would seriously have some issues. And I am able to think in my own terms outside of net-land, it's just when I've only a few hours online, I'm going to enjoy myself and emmerse myself in a little bit of unreality (because you know, net.. lol serious business)
