An addendum to Doctor Fullham's post, and to reply to some stuff you've said. I would like to forewarn that I may be a little sharpish in my reply, we don't do this because we're trying to be mean and make people cry, but to ensure that the presenter of ideas understands what is flawed within their proposal and makes adjustments that can allow the idea to become something much more improved and up to the high standard that SCP authors are expected to have in this day and age. Whether you take on suggestions or critcisms is in your hands, you're not oblieged to listen to what we say, but if you want your piece to reach the point where it's officially designated, then you'd do well to heed.
I understand that you are new, at least in terms of the writing side, but in my honest opinion, you would have to write something astonishingly unique and well crafted to have a chance at the 5000 slot. I unfortunately don't believe this concept would reach that without vast edits to what you've presented. Create a more realistic goal to start with, then build up, you can't run before you've walked.
The anomaly is a must in these things, and in your initial post you did not make it entirely clear what the anomaly was. You mentioned a story with multiple things that could be an anomaly, but not said what one is the actual anomaly. A missing person's case with anomalous factors isn't an anomaly in and of itself. The closest thing I could associate it to is an SCP I can't recall the designation of, but it's a subway train that occasionally enters our reality, then when it leaves the station it leaves our reality.
I've never played Silent Hill myself (I know, I'll get around to it) so I'm taking Fullham's word for this. Don't ever copy or have articles heavily related to a specific game/book/movie unless the anomaly is somehow based around it. From what I can see, this is more a tale than an SCP in its own right.
