Anyone ever play a game called Chrono Cross? That shit is ill. Its got two parallel alternate relaties in it and you can go back and forth between them.

And you play as a guy who died in the alternate reality, but lived in his home reality. And theres sometimes the same people in the alternate reality, but they're completely different. Like this one girl in the home reality writes poems and shit, and you can get a poem off her and then go show it to the same girl in the other reality, and there she is all busy and only concerned with working, and then you show her the poem and shes like whoa.
