...did you seriously just try and cite examples of abnormal psychology as groundwork to justify highly unlikely physical events?
Try? I thought I did.
Actually, only 2/3 of those examples were abnormal psychology. The third was an outside effect, albeit, I wouldn't call members of a cult psychologically stable.
Although, why wouldn't abnormal psych be related to unlikely physical events? These are examples of what's in-game, but they're really no stranger than stuff that happens in real life.
A good example would even be a man who was just recently convicted here for the murder of six women
... and possibly 20 others (even though he told an undercover police officer he wanted to make it 'an even 50). He was a pig farmer, and he was witnessed to've hung the prostitutes on meat hooks while he slaughtered them in his slaughterhouse. Evidence basically says he stuffed the bodies into pigs and into waste barrels that were sent off to rendering plants and also fed to the pigs/ground up with pig meat to be fed to customers. They found heads, hands, and feet scattered around his farm. He said he would've gotten away with it, had he not been "sloppy".
Abnormal psychology can create all sorts of unlikely, strange, or disturbing instances... whether it's the psychology of an individual who has been abused, a serial killer, or something like PTSD... and Silent Hill feeds off of all sorts of insanitites and psychological disorders. So, yeah. I'd say it's justified.
