The structure of the room is square, 

The walls long, white and bare.

There are no windows

The door stays locked. 

I'm told that it's a place for me to stay safe.

away from the dangers of the world. 

I sit on the floor, cold and made of stone.

I stare and feel myself being approached. 

the walls draw close.

The door opens and in front of me is the world

With all the structure of the room, yet vast and small at the same time.
