I am currently rewatching "Strangers From Hell" and MY OH MY... I almost forgot, when I first watched it, how it pushed me towards madness and the sleepless nights were unbearable.
I can relate to Jung Woo on so many levels. I too can feel how slowly and creepily all those thoughts are surrounding me. I am almost afraid of myself.
These characters are all real. Like REALLY real. The world is full of them. WE ARE THEM. If this thought doesn't scare you, I don't know what will.
