Tip #80: Description in horror

what we’re trying to do in modern horror, is not describe the creatures or the events, but the emotional events that follow those, whether it’s their immediate insanity or fleeing in terror.  The best writers, I think, are the ones who can best match the reactions of their characters to the reactions of their readers.
