Whoa, whoa, whoa - - this here is heaping pile of misinformation. Multiple Personality disorder is a real condition that real people suffer from where they can have separate personalities in the same brain, each with it's own memories, it is NOT a made up thing from the movies. And Bipolar Disorder has absolutely NOTHING to do with multiple personalities, but is another real condition where the sufferer experiences manic highs and depressive lows.
