This black goo substance that is accumulating on the ocean floor was discovered, and I see that when scientists initially came into contact with it they became very sick (Morgellons). It was realized then that this substance could be used in minute amounts as an effective (non blatant) chemical weapon.
The substance itself wasn't created or invented, and the real "art" they were trying to discover was how to administer it to designated areas. I get that some people are immune to this substance too, which created an even greater curiosity (and also the realization that a cure could be made).
I don't see it tied to our thoughts, and the karma feels tied to the earth (or those trying to take over the earth as some kind of man made / natural defense). It does have a certain magnetic property to it, but I don't see life to it. I get the reason it is in sci-fi movies is because of the instant (and violent) reactions it can cause. It is very mysterious in appearance, texture and effectiveness. The slightest exposure can effect the nervous system almost immediately.
Q. What are the strings that appear in the skin (like threads)?
A. When the body is exposed to the toxin I see a skin reaction occur, and in more extreme cases open sores start to form. I get these sores have a "smell" to them that may not be blatant to humans, but certain parasites are drawn to them when they are in the open air. (I get an image of fruit flies being drawn to cider vinegar.) These parasites are all around but the sores in conjunction with the altered body chemistry makes what would normally be something benign in our environment into something toxic. These parasites get into the irritated skin sores and start laying eggs, and make more parasites. I get the more mature parasites have the visual appearance of thread (I see it like a worm in my mind).
(I also get that if you suspect you have this condition, cover any skin irritation, even with vaseline to prevent these parasites from getting into your body. This will greatly increase chances of recovery.)
A. I see Harald Kautz Vella as being genuine and he does have a cure. It isn't 100% effective, slow to work, but definitely is making strides in this area. I see his idea being based on homeopathic theories that you need to treat like with like, just a much more milder form of it (similar to how immunization work). If you take black goo and highly dilute it (or extract something from it) you can slowly give it to the patient and let their immune system build a response to it. I see that once it is effective, the body will "push out" the toxin and parasites that react to it through the skin (looks much worse before it gets better), but there is hope of a recovery.
