Keith Laumer, The walls (1962)
“ She had to get hold of herself. These were only mirrors—she knew that. Only mirrors. The other women—they were mere reflections. Even the hostile ones who hid the others—they were herself, mirrored in the walls.She opened her eyes. She knew there were joints in the glassy wall; all she had to do was find them, and the illusion of the endless plain would collapse. There—that thin black line, like a wire stretched from floor to ceiling—that was a corner of the room. She was not lost in an infinitude of weeping women on a vast plain; she was right there, in her own apartment—alone. ”
