There was an older version of you that used to be here. He worked in the hospital. And then he vanished and now you're here in his place. The people at the hospital, a place he worked at, are trying to get a hold of him and they got through to you. You've probably got his phone. Understand? They think you're him. Technically they're right, you are, but you don't know anything about your older selves experiences of this place.
