This one’s tough… But I think I’ll settle with a place where you hear voices. If you really think about it, that might one of the worst kinds of psychological terror. You’ll hear voices, and you won’t know where they’re coming from or how to make them go away. You’ll have no idea if there’s actually people close by or if it’s just someone or something messing with your head. You’ll have no idea if you’re alone and hearing things or if the voices are real. And by the time you find out, it will more than likely be too late. The thing causing it all will have finally lured you into its trap or simply driven you insane.
