My mom and I saw the sky move.

I was taking my dogs out in the backyard to go to the bathroom when I looked up to the sky.
It looked as though all the stars that are usually there were moving South, then it occurred to me that these were indeed UFO’s heading south in a pattern, one after another. Not in a straight line but a pattern I can’t describe.They covered the whole night sky. It was the strangest thing. I counted up to 30 and lost count from there but for 10 minutes I stood there trying to comprehend what I was witnessing as i’ve never seen such a large amount / a steady stream of them going in the same direction. I brought my mom outside, who doesn’t believe in UFO’s and she just stood there in a trance, I kept saying look at them all and she was silent, and said “wow, there’s so many of them!” They were very high, circular ,white glowing dots in the sky which would appear to the naked eye as looking like a satellite moving, but the speed and sudden stop and then go faster and in a different direction.
I’ve been a believer and witnessed many UFO’s sightings in my life, but nothing compares to the amount, the sudden quickness and disappear and reappearing, all heading South.
