SCP Foundation

The first SCP idea I ever had (long before joining this site) was for a type of disease. At first, the idea was to have a disease the spread through psychological means. It then went to a virus that affected you if you saw an infected host. It went through a few more phases of that such as: spreading through a phrase, spreading through a mindset, spreading through sound. I'm saying all this so you can understand where I was coming from and maybe where I went wrong.

What I eventually settled on was a disease that formed a wormhole in the skull of its victims, and looking into the "portal" was how it spread. The "portal" would also emit a sound that terrified those who heard it to the point that they would do anything to destroy it, getting infected along the way. The "virus" kept its hosts stable through unknown means, keeping the portal exposed through the eyes and mouth, infecting onlookers. People who are partially to completely deaf and/or blind are immune.

I think I like this idea because of the aesthetic of the horror. Having something with its mouth and eyes open wide, nothing behind it but a black formless void being the last thing you see before being infected. Though, there are a lot of problems from here, a lot of questions I don't would have to answer. I don't know if the idea is worth my time, or if I'm even skilled enough to tastefully put it into words. I'm open to any sort of feedback, even if you just want to shut the idea down. I've got plenty of other ideas to get started on, but I can't bring myself to make a decision on this one.
Thanks!

I liked your first paragraph specifically

It went through a few more phases of that such as spreading through a phrase, spreading through a mindset, spreading through sound.

what your referring to is a memetic virus something that I think hasn't been fleshed out completely or properly yet, it's a very interesting and fun idea to play around with. It influences someone's thoughts and can spread through people infected through speech and implants a mindset. People have actually written papers about it such as "Viruses of The Mind."You might want to read it if you chose to do a memetic virus. But I think you just copy Dr. Who with the second and 3rd paragraph it's been done and you should probably just cut those ideas it's confusing and slightly dull. People are most of all scared of the unknown something not as obvious something that spreads through populations. Something that makes you wonder whos thoughts are whos and if you even have independent thought and free will at all. Fear of the unknown is the greatest fear of all. Black voids may be scary but fear of the unknown wins without a doubt.It's an interesting concept, so keep at it!!! Good Luck!!!
