A strange recurring dream

To keep with tradition, I drew this in class. I was trying to remember how to do vanishing points I learned in school.

I start in the morning in a cavernous station with large, looming windows. You look out the window and all there is to see is sky in all directions, like we're suspended from a suspension bridge or long floating isthmus. It reminds me of a futuristic port - there are moving sidewalks taking immense numbers of people to and fro. No time to take in details. There's a sense of urgency to catch the train, plane, automobile, whatever it is. It's disorienting yet very remarkable.
