I'm no fan of horror movies but I watched them all the same because I also learn a lot from it,I learn how to tackle horrifying scene through watching horror movies. I hardly even get scare because I know I just have to be brave to pull through any scene like that.
I learn defence mechanism from watching horror movies, the antagonist always gives some defence skills that we can learn from and this can be used to tackle life attacks any day.
Watching horror can help one to fight stress because some horror movies shows how one can still be calm and relax even in the face of strange and scary situation. Despite it weirdness horror movies is a must watch once in a while.
