Anomalylike noise of an aircraft flying over, but never moving, staying in one place Last night, 8/28/2021 -8/29/2021 was the first time it lasted long enough to make me think I was going insane. I'm recording the experience. I didn't record before, so I don't want to answer anything incorrectly. I've heard this several times in the past. Don't recall the dates, duration, or actual frequency. I will record from this time forward. I ran around the house for three hours turning off every possible electrical source. I repeatedly checked my furnace, even though it was off. I unplugged all electrical fans and air purifiers, anything emitting a sound except refrigerator.
