Inspiration or Confirmation

Many authors have entire worlds growing in their heads. The stories that are written down are simply the tip of the iceberg. The most solid points that show in a swirling ocean of ideas and concepts. Even for a single story there is a great mass that exists below the level of a single book. With the way the internet has connected the world this can lead to fascinating moments. An idea or a concept that has existed for years in an author's mind suddenly appears for a brief moment in the outside world. The idea has never been spoken, or written. There it is someone had the same strange fancy.
 This author had one of those moments today.
