I was at home and saw tv with my parents. When I looked out the window, I saw many (20+/-) light balls. I showed my parents. They flew over the village up on the field. I went with my mother to another window and saw that they stopped all parallel. Suddenly the lights were off. I was afraid. They looked like flying lights and pulsing. They weakened the lights again. You could not see what was behind the light. I did not see so far back. I made a video, but I put it out after a few weeks back, it because you could not see anything and the lights made no noise.
