I never expected I would be doing this but as it has me a little disturbed, I will do my best to explain it adequately. I was in my room, I couldn't sleep and was thinking about getting up and reading or watching a movie, just laying there considering. I first noticed the noise, close but what threw me off is that I hadn't heard it approaching. I had NO idea what this was when I first heard it, I was just as baffled from the beginning as I was at the end of this experience. When I first heard it, it sounded above the house. A kind of humming, that doesn't really describe it, but it's the best I have. It would seem to move around the town, sometimes closer, sometimes further off. I felt startled and worried, not really scared at first as I thought looking out a window would shed light on whatever this was and surely it would be something logical. However, I looked out every window and continued to see nothing. I could hear it but not see it. Then I was a bit frightened. My dogs were going crazy the entire time. Plus through-out the day, one of them, that rarely barks, every time I have let him outside, he has run the perimeter of the fence, barking his head off. Towards the end of this sightings I started feeling a little "fuzzy" for lack of a better term. Today I am nauseous and somewhat shakey.(I should have checked "physical"). I am definitely confused as to what this was. This lasted about an hour, maybe a little over. At least that is when I stopped hearing it.
