I dreamt the booths were all empty except one

I'm walking through the old UN basement, the one with the glass interpreters' booths, and every single one is dark except the last — where a woman is translating a speech that hasn't been given yet. She looks up at me through the glass and mouths the words I was about to say myself. Nobody else is in the building, but the whole place is humming like a room right after someone leaves.
