Here is why I am asking this. I am entering a short story into a contest (Writers of the Future). Most of my ideas are novel length ideas that can't be smooshed into 30 pages. However, I had a dream one night, and I woke up and wrote my entire dream down. Now I am evolving it into a short story. It's short enough and will be the right length. It's a sci-fi story and has to do with the world ending (sort of) and some people making their peace before it's over. There is some stuff missing though: 1. Antagonist. There isn't really a powerful antagonist bent on destroying or stopping anyone from doing anything. 2. Conflict. The story is so short that there isn't much conflict. However, there is a main character, with a desire, and there is conflict up until he gets it. But I feel that, in the short span of pages, I am rushed into all these things. Does it matter if a short story contains a powerful antagonistic force that is upsetting the protagonist's life and stopping him from getting what he wants? I am trying to inject much more conflict into the story as I can, but are people more lenient with short stories? Or does everything that apply to a Novel apply to a short story as well? Sorry if that question is confusing. I assume the answer is "yes", and every story must have the same elements to be successful. But I am more wondering about the intensity (and density) of the conflict, and if it has to equal a Novel in power.
