How would you feel if someone knocked on your door, and it was the physical personification of your inner voice?

So there you are, just doing your daily business, watching a movie, eating a sandwich, reading a book, etc. and then there is a knock at the door. You get up to let whoever it is in, expecting it to be a friend, significant other, whoever... and then you notice something strange. This person looks like you. Not just a little, *a lot*. So much in fact, you can't even tell the difference. You begin to suspect that this is you, but... from what timeframe? How are you here at your current door? Just as you are having these thoughts, the person in the doorway speaks.<br><br>"Just let me in... I know everything about you."<br><br>How would you react to this?
