We were watching shooting stars since there were many on the night from the 12th to the 13th, from around 2:30am to 3:45am. We were watching the sky from a lawn and we were alone. Someone with a flashlight annoyed us from quite a distance but he disappeared.At first we saw something triangle shaped flying Northeast around 50 meters above us, floating, no sound, nothing. While it was hard to see it couldnt have been a bird, a bat is highly unlikely because the movement was very smooth and it had a very geometrical look.Then we saw something else, something moving, like a plane. But it had no blinking lights and made sudden 90º movements. It looked like a star, but upon further inspection it had barely visible tentacles around it, but very fine and detailed, we are 2 witnesses. They moved away and slowly disappeared and got more and more transparent. There were multiple ones, around 5-6, sometimes dangerously close to each others.While I was scared, my friend was more excited about it. We tried to explain it in any way, but it seems impossible. Nothing can move like that. While following a path it did irregular movements.We lost sight because it slowly went away from above us to somewhere else, the lightsmog made it fade away.
