They're empty first of all. And anything or anyone that appears to be there, isn't actually there, you-- are dreaming. Don't believe me?
Let's play a game, it's called, "Where's Waldo?" With you as "Waldo". Yes, that's right, you-- have to find yourself in this sea of walls, floors and people you do not know.
These people, with stoic faces, walk the same halls, looking for the same thing. They do not care that you are here, and you don't care that they are here.
Just get to the end of the hallway, but don't go into the light, you are not here to die -- you can't. You have to find yourself before you do. But there are some people who die before finding themselves in the "Where's Waldo?" page.
They're dead!
Out of this maze of halls you find yourself in.
But you...
You are determined. You will not leave without finding yourself, do not allow yourself to give up!
Look!
At the end of the hall! It's you!
You found yourself! You win the search! Now go!
Run! Get to them, yourself is waiting for you at the end of this hall.
RUN! Run as fast as your legs can carry you! Because you do not have time to think, so RUN!
They need you to save them! They're calling out to you, screaming for help, for You.
Get to them, grab their hand, save them!
...And just as you barely make contact with their hand and lock eyes with a body with the same eyes and face as you...
They begin to fade, to disappear!! WAIT!NO!
Come Back!!
You were so close to saving them!
You wake up.
It was all just a dream.
You were dreaming right? You know you were dreaming!
