I have some crazy nightmares. Often I write them out to try to make sense of them, and to make them less scary and haunting. The act of writing them out helps, but what’s even better is the fact that they are usually the seeds of stories.
Sometimes the image from the dream that birthed a story is the hardest scene to cut from a completed tale. But I am pretty sure that about 80% of my stories come from my dreams. Is it little wonder that I write science fiction and fantasy?
