The cramped space and the stale air reminded Olivia of the old attic she used to play in as a child. She remembered the scent of dust and forgotten treasures, the way the sunlight would stream through the cracks in the boarded-up windows. She felt the phantom pressure of the wooden floorboards beneath her feet.

"This is awful," sighed Tom, her coworker, looking increasingly pale.

Olivia didn't say anything. She was busy reliving the joy of her childhood games. She could almost feel the rough texture of the old toys in her hands, the thrill of discovery, the secret world she had created within that space.

A wave of yearning washed over her. She wanted to go back, to be that carefree child again, to feel that sense of wonder.
