I don't believe that a writer 'gets' (takes into the head) an 'idea' (some sort of mental object) 'from' somewhere, and then turns it into words, and writes them on paper. At least in my experience, it doesn't work that way. The stuff has to be transformed into oneself, it has to be composted, before it can grow into a story.
