I was on the way home from study trip and when i looked outside from the bus i saw a light that i thought it was a plane but then i saw another lights and they flew really close that i thought planes wouldn't flew next to another planes that close. then i started thinkng that it was drones. but after 5 minutes watching them, i realized that noone would flew that big amounts of drones. i couldn't count that time because i think i saw more than 50 lights that hovering through the sky. i told my friend and they were joking about ufos because it was weird and it wasn't even stars, they moved without any directions.
