"Horror" movies do not have any effect on me at all. Nope, don't mean to sound like a badass but pop horror is fiction.
Real life shit is terrifying because it exists, right alongside us, and these terrify the shit out of me. For example:
Dictatorship, Paranoia, Famine. Welcome to North Korea:
You must wake up at 6:30AM every morning to report to your state mandated assignment, and a citywide alarm playing "patriotic" and solemn military music will remind you to.
The TV set in your apartment is fitted with audio and video equipment that watches and listens to everything going on, transmitting directly to your local police division.
The TV must also be tuned to the state media channel at all hours of the day.
You must put on an expression of crying during the national day of mourning for the past dictators or you will be arrested.
You are given food vouchers only allowing you to barely get fed.
Even as you are starving and shivering in the brutal winter, police with batons and riot gear barge into your apartment to make sure that the portrait of the Glorious Comrade Dear Leader that you are required to keep clean and free of dust on your wall is upkept.
Starvation, illness, compliance raids, periodic mass arrests to keep everybody in line, constant reminders that everything you do or say is monitored 24/7/365. The radio and TV drilling these things into you, flat out telling you that nothing escapes the Glorious Comrade's eyes...
This is not from some demented fantasy and sci-fi land. This is currently happening right now.
