Hi Nate,
Actually I think things like this occur more often then you think, whether it's a smoke, noise, lights, dog barking, etc with a neighbor. As I said in one of my previous post, we had a neighbor blasting music and when my wife asked them to turn it down, they cranked it up. Then they started playing music 2AM. This went on for months. Then to other dilemma is what do you do about it? Hope it fizzles, call the cops, go over there with a baseball bat.
Another house we lived at, the neighbors decided to hot tub and drink at 2AM, which of course was 10 feet from our bedroom windows. Again, this went on almost every night for months. I did speak to them, they were nice, but no resolution. Fortunately, we were renting and about to move anyways.
Sorry to read about your issue, hopefully if this doesn't get resolved you'll find peace in your next place. Daily worry/anxiety about these issues is bad for your health.
