Bright beam of light above tent, no sound, dancing flickering lights on side of tent.While camping husband, Grandchild and myself went to the tent around 1:00am. All of a sudden I woke up to a bright light above the tent, (bright spot light or beam of light) the whole top was lite. There was also flickering dancing lights on side of tent, I would say at least 10 more lights. No sound; whenever lights were done it was like a light switch turned off. The whole time lights were outside, I suffered a terrible headache, and it went away 5 minutes after lights left.
