I was driving and this bright firework-like shine got my attention. i soon realised it had to be something else, because there were no explosions to see. and helicopters would never be able to fly that close... about 20-30 lights pulsing in the sky, hovering amongst themselves... doing some weird formations and slowly disappearing behind each other... it all happened within a minute... so bad there is nothing to show... by the time i managed to get to my phone's cam, it was gone... i guess i was so overwhelmed by what i saw... i did't really know what to do... if i should stop the car or turn the cam on while driving, and at the same time starring at this weird thing in the sky and trying not to cause any accident... it all happened within a minute, and after slowly vanishing behind themselves, a last pulsating weak dot disappeared... i surely was not the only one who saw it! there were at least 10 cars driving in the same direction i was heading to.
