THE YELLOW WALLPAPER (1892) horror short story. A woman suffering from nerveous depression has been confined to her bedroom - a cure prescriped by her husband. There, she developes a strange fixation on her bedroom wallpaper. Sure, there's feminist themes and all that, but what I really love is the basic idea of creating a horror story about a person staring at wallpaper. Genius!
This short story really shows the strength of litterature - it is hard to imagine a story like that in any other medium. Nevertheless, it was addapted into a movie in 1989 and 2011.
