Hear Your Electromagnetic Waves

I had a long, long dream. The world in the dream was virtual, but it was so clear and audible that it was almost impossible to recognize it. Ordinary cross streets, with endless streams of people and cars coming and going. But there was only one girl who really paid attention to me. She passed through the crowd quietly along the stream of light. Even if she passed each other, her eyes still had no image of any object, not even a flicker of it. She just walked through the cross streets calmly. She couldn't see anyone, just like no one could see her.
