Bright light glides over my houseI am really freaked out right now. It was about 10:00 p.m. and dark outside and I was on the front porch (facing west), talking on the phone when all of a sudden there was a bright (kind of fluorescent) light that came over the house from the back and it went halfway out to my yard. There was no sound of airplanes, or helicopters, nothing. It was dead silent - that's what is so weird. Everything was lit up for about 10 seconds. Then it was gone. As the light was coming over the house and in the front yard, where the light met the darkness, it kept in a straight line - really weird! I did not see anything in the sky - I was to freaked out.My house is kind of secluded with lots of land around it. I have 2 neighbors, but they would really think I'm nuts if I told them this.This was like a scene from a science fiction movie and I don't even like those kind of movies! I'm not crazy, I know what I saw and I have never believed in UFO's. Is there another explanation?? What could this have been? Any help would be greatly appreciated. Thanks
