Some odd little scene may be perfectly happy to just be an odd little scene camped out in your journal forever. My mind starts to explain the soggy dog sighting. Images ARE stories. Stories are paintings. Every word is a color waiting to be splashed on the blank canvas of your journal.
Adjectives are vivid colors.
Verbs are streaks of paint that add motion to the story. Nouns are dashes of light and dark making forms emerge. A star silently hung to sigh. In the purple sky. Close your eyes and imagine it.
