The High Pitch Sounds that Won't Go Away!

We've been hearing high pitch sounds around the world. Many people have been reporting the same thing and looking for the answer as to what it is and exactly how to make it stop. It's annoying, it's deafening and it's driving folks crazy. I can't say I blame them because I'm suffering from it as well. I first noticed the sound when the Moon would rise into the heavens above. Then I started to realize the sounds were happening at pretty much the same time every night. Thirdly, I've discovered that the sound we are hearing happens just before I see holographic imagery and strange messages in the skies or in the trees and bushes. What the heck is going on and how much longer are we going to have to put up with this?
