She looked in.

The window opened up on another world, a place she had never seen... She looked in, and fell into it's depths.
She was lying in what she knew to be a forest, having seen pictures of them in their last days. The leaves above swayed gently in the breeze, turning the ground into a great pattern of filtered sunlight. Flowers blossomed all around her, filling the air with a perfume that didn't seem quite right. Somehow, it was fake. A scent like something you might spray from a bottle.
Ignoring this flaw, she got up from the leaf litter she had been lying on, and watched as a four-legged creature stepped daintily towards her. Deer, she thought, and stroked its velvety nose. Birds tittered in the trees above, their melodic calls awing her.
She had never heard birds before.
The deer walked away, then glanced back, as if willing her to follow. Its soulful brown eyes appeared slightly glassy, but that didn't matter. She strode after it, following along twisting forest paths. Eventually it stopped before a bubbling stream. The water was clear and pure, and the sound of it rushing over the rocky bed was like millions of tiny bells. Wrong, said a voice in her head, but once again she ignored it.
Small fish darted toward her as she stepped into the stream's depths, tickling her bare feet. The deer bent its head and drank, and she had a sudden urge to do the same. But she couldn't, she knew she couldn't. If she did she would be thrust away from this place, and she didn't have enough money to return.
The world around her had already begun to darken and disappear. She sighed, annoyed. Surely it hadn't been fifteen minutes already?
"I'm sorry." Said a metallic voice from above, "Your session is over."
The Virtual Reality booth materialized around her. She pulled off the VR goggles, and stepped out into the world of plastic and metal. The world where there were no forests, no birds, no deer, left. She exited the Arcade and looked up at the sky, comparing the swirling darkness to the bright blue of the fake forest. Had it really been like that, all those years ago? Or was it, like the Politicians said, all just a tale told to make the human race seem evil?
She supposed that she would never know.
