Supernatural/paranormal activity and the power of suggestion

I don't think I have ever really believed otherwise. But that didn't stop me as a teenager being absolutely scared shitless by films like Omen, the Exorcist, Children of the Corn etc. etc.. Zombies, vampires, ghosts, demons, possessions, Apocalyptic world ending stories and all that malarky I really did find genuinely scarey despite wholly accepting the idea that it wasn't real. For whatever reason that knowledge just didn't allay the fear that films and books about these things inspired in me.These days not so much. In fact I can quite happily watch a horror film or read a horror story alone at night and then switch the light off and go to sleep with barely a second thought.I don't know what happened. I just sorta grew out of it. These days the rare nightmares that genuinely terrify me invariably involve terrible but not usually fantastical things happening to my kids and suchlike. Much more mundane and all the more disconcerting because of that. Well a large amount of EvC debate is between those who consider this the blatantly evidenced conclusion and those who insist that there is some reason to consider some supernatural beliefs as more worthy of genuine consideration.But if there is more to these claims than things like argumentum ad populum (so many people believe these things that there must be something in them), argument from authority (some renowned scientist believes in the supernatural so there must be something to it) or personal experiences that the person believes are the result of supernatural encounters (in effect citing belief as a form of evidence upon which to believe) then I have yet to hear them.

From an evolutionary standpoint, wouldn't the human animal be wired for survival instinct? If so, being alone in a building where you know that nobody can help you were you attacked,coupled with reminders from the scary stories--be enough to put you on edge walking through dark hallways?

The only "unknown" that scares me is unknown humans. I live right across the tracks from "the hood" and I hesitate to walk through there in broad daylight, much less at night. My fear is no doubt irrational, based on the low level of actual danger involved.
