Why is horror scary to some people and why do other people love it?

             "Some people may like scary movies because they enjoy the adrenaline rush of being scared while being safe, Cantor said. “Some people like anything that gets their minds off their own problems,” she said. Individuals who are highly empathetic may not like scary movies, she said." (PsychCentral)

So some like the adrenaline rush, and others may not.

As a person who likes horror movies, I say it's probably because we know it's fake, like the make-up and costumes and the other stuff. We don't get scared easily because it's all fake, some people who don't enjoy scary movies could be highly empathetic can be overstimulated by what they see.

I don't know if that's the reason so sorry if you don't get it.

sorry, wrong answer!
