She stepped into the revolving door. As she pushed, the hum and pulse of the city hushed. The light dimmed. The air cleared of muggy heat. The stink of cars and trash dissipated.
A world grew in the space between doorways, a gap in which she stood encased entirely in the glass. Beyond the glass on every side, she saw waterfalls tumbling down misty mountains with dragons perched on their peeks. Unicorns galloped by ridden by elves with flowing cloaks made of leaves.
She pushed the door farther and a gust of air conditioned office air blew away the world within the glass. Beyond the opening in the door, she saw a bored security guard, a television playing the news, a bank of elevators.
She turned around, returning to the world in the glass.
