This has probably been asked before, but what is your method for creating a plot? I tend to write short horror / dark fiction. Many times, I'll have a "what if" moment, as in: "what if the pizza delivery guy were a vampire?" then I'll work from there, trying to imagine how my protagonist would deal with the situation. Many times, a twist ending will pop into my head, as in: "what if a man were responsible for the death of his mother by proxy?" Then I'd work backwards to the beginning of the story. Do you have a certain method you've recognized?
