I wonder what would happen if somebody "formed a connection" with a person from our world? What if it was with a person who themselves had a bunch of people stuck in their head?! Would that constitute crossing the streams?

Also, I'm starting to think I should stop fanboying a certain game before I "form a connection" and get the urge to go around punching things a lot and building a fortress in my back garden. Wait, I already have the former... OH NO I HOPE IT'S NOT TOO LATE
