there were about 15 of them in groups of three in each direction we looked in but high up in the sky, some of the lights were blinking

i was smoking with my friend on the roof and the sky was clear, no clouds in sight, and we spotted these lights moving really fast through the sky and then we spotted another one and there were so many, they were faster than helicopters or planes and they were close to the stars so too high up for planes. some of them formed triangles, and some of them were just flying around. some of them had lights blinking red and white and some were still white or still red. we couldn’t identify a shape, they just looked like spheres with lights.
