Not only of a dark place but also people with dark souls scares me. Though I haven't met someone who's dark inside enough to freak me out. I have a sister who is known to our family who can see dark people or lets say spirit realm. And I hate hearing her stories. And whenever she talks about it. I would just dismiss it as something not to be given too much attention. So as not to scare us all and not to make an issue of it. The more you give attentions to it the more you become intact with the darkness.
