tl/dr a guy kept hearing loud BOOM noises in rural Idaho, primarily at night and so loud it shakes his windows. He made a couple of tiktok videos about it and police told him to stop looking into it and he did a "taken hostage" style video where he sheepishly talks about "science". I've heard about this in NM/AZ and some other states as well with the usual details including window shaking.

Another interesting sound is constant humming with no discernable source that can go off and on for weeks or months at a time.

One reason I want SkyHub. The humming is a vibration I feel, many abductees relate. I’m out after. It is noticeable to people on next street, not just me hearing it. We have lake/wetlands directly behind us. I have seen craft hover over it, others have.

The humming is real for many abductees. Even neighbors hear it. Blue lights are too; it can cause PTSD that affects you when you see police blue lights at nigh

I suspect it's a mix of underground activities and overhead cloaked activities

Here's an example of a mystery boom:

I also note that not all microphones can capture the humming noises either partially or completely - what gets recorded doesn't fully match personal experience
