Nightmares exist outside of logic, and there’s little fun to be had in explanations; they’re antithetical to the poetry of fear
I LOVE this quote and agree with it whole-heartily. We fear the unknown, the things we don’t (or can’t) understand. Once we understand how something works or what something is we lose that fear and/or respect.
In entertainment, whether it be books/movies/etc, the things that stick with me are the things that remain mysterious. The unfortunate thing is that humans tend to be so inquisitive that we want to know more. Take away that mystery and more often then not things turn mundane.
Take the TV show Lost for example. I LOVED this show. It was a very mysterious show & every time it gave you an answer it created another question. The problem is that in the last season of the show it started to explain a few things, and once explained those things tended to be underwhelming. When the show ended it didn’t answer all the questions which upset a lot of people.
So the interesting question is do you take away that mystery by giving the reader answers there-by robbing them of their interest and/or fear? Or do you keep the mystery and possibly leave an unsatisfied reader?
