This is right out of the Mothman Prophecies. Very odd and creepy story from near the Fukushima nuclear plants, about a month before they exploded.
Wow. This story just gave me the chills. When I was seventeen, myself and two girlfriends were at my friend's house when I got up to go to the bathroom. They called me back before I could go to look at a huge moth circling a light fixture in a bedroom. We were all in the hall looking toward this moth when we heard a frightening whispery sound next to us. We all screamed in fear and ran out of the house. At the time I don't think any of us had heard of "mothman".
