Some things that happen in life are so horrific, we don’t know how to talk about them (still learning how to talk about trauma as a society), we turn them into fiction.
But even in fiction sometimes it’s too horrific most most readers, and they turn away.
How to tell your tale while staring true to its horror and yet get the readers excited about it?
Shroud horror in comedy. Hide it under humor. Present it as something funny when it’s not funny at all.
Monty Python were masters of that. Study their sketches.
And in your own writing, when you have a scene that looks straight out of a horror movie, make the characters say something silly, or spill something on themselves, or bump into something, or fart. Whatever it takes.
Because your story needs to be heard, and if comedy is what’ll do the job, do it.
