Room?

I had a dream where I was in an argument and my position was "A hallway IS a room". I soon became aware I had very little evidence to back this up, especially considering how much conviction as I was putting into defending it. So I ran away. You know how once you start running in a dream sometimes it just becomes a running dream. So now I'm running down one of those never ending scooby doo hallways where you pass by the same painting 3 times. I thought to myself, "This is too substantial not to be considered it's own room."
