A Connection to the Real World! (2)

So I'm really not a fan of video games at all, but all this talk about parallel realities and evil geniuses got me really interested. I was on the internet the other day and found the preview for a video game called Silent Hill: Downpour. A little dig helped me find the entire series, and eventually the original game in this perpetual series, entitled Silent Hill, in which the plot caught my eye.


The video game tells the story of Harry Mason, who crashes his car after swerving off the road to avoid a girl. When he wakes up, his daughter is missing. Upon investigation, he learns he is in a town called Silent Hill. Later in the story, we learn that the city itself is a portal to the "Otherworld", which is filled with demons and monsters. Throughout the rest of the plot, Mason has to save Silent Hill from this parallel universe.


This really got me thinking. Is it possible that there are places like this in the real world? Is it possible that certain cities or places on the planet are portals, or gateways to another dimension? If so, what effects could that have on our lives today if these gateways were discovered?
