When you reach the editing stage, it is often the case that you can get too involved with the story to detect errors. You can see words in your head that aren't actually there on the page, sentences blur together and errors escape you, and you follow plot threads and see only the images in your skull.
This quote highlights the common challenge faced during the editing process: being too close to the work to spot mistakes. It's easy to overlook errors when your mind fills in gaps or visualizes the story as you imagine it, rather than as it appears on the page. Taking a step back, possibly with fresh eyes or through a different perspective, is crucial to identify overlooked errors and improve clarity. The metaphor of following plot threads and seeing only images in your skull underscores how creative involvement can paradoxically hinder objective editing, emphasizing the importance of deliberate revision strategies.
