here mind, where'd you go?

I must be missing something, surely? Did I fall off the face of the earth only to find myself in place of a person I don't seem to know - surrounded by people I also don't seem to know much about...? I wonder if they know much about me, if even I can't seem to figure me out? I feel like I've been blasted with amnesia, or something of the sort - as I can not make sense of any of this. It's like I'm stuck in a dream - all disorientated and in a fog. I just want to wake up to find my mind back in it's proper place... I suppose that's asking a lot.
