Binary Oppositions in Horror

Often in horror films there is a binary opposition of calm vs. chaos. At the start of the film it's often calm, maybe a family moving in to a new house on a sunny day and having fun vs. the middle to end of the film where there is chaos.

This opposition can also be seen sometimes in horror titles and posters for example...

The silence of the lambs; this is not an unpleasant looking poster because of the butterfly .

Films which don't necessarily sound like horror films/ they sound pleasant :

Prom night, the ring...

PROM NIGHT - end 

PROM NIGHT- beginning

I definitely want to include this structural pattern in my horror film as it helps with the narrative of the film and thus helps people to keep up.
