Funny you should mention that but I watched a video posted in here the other day talking about humanity being subjected to emanations to raise its frequency or something like that. The famous chaneller in the video Deloris Cannon said that lots of people complain about the ringing in their ears and she said that you can ask 'them' to tone it down a bit. It was an approach to what is going on that I am not knowledgeable about and feel disinclined to follow up at the moment, hence my vagueness. But your question reminded me of those statements.
I have recently been plagued with ringing in my own ears but I have so many health problems that it could have any one of a dozen totally mundane causes. I feel wrecked because my sleep seems to be interfered with but again there are much simpler explanations than outside influences. However I again recently discovered listening to Linda Moulton Howe in here that many people are reporting apocalyptic dreams with the sky on fire and floods. I had just such a dream of dark clouds laced with fire rushing overhead and a mighty tsunami rushing in from the other direction. It was just ahead of theTonga disaster so I associated it with that.
Here is the thing I referred to 6 or 7 videos down from the top of the Forum topic:
Investigation into what may happen by 2050
2.28 into video of:
Hums, rumbles and groaning sounds, booms, of uncertain origins are also experienced as mass events that can go on for extended periods of time and are reported from all over the world. So, not an answer from Courtney but you can rest assured many others experience similar phenomena.
