I live in NJ/in 2020 I had just walked out of my local ShopRite store during the day when I happened to glance up in the sky & noticed high up right below some overcast clouds a cluster of what appeared to be from my vantage point a small cluster of dark orbs that were swirling around each other in a erratic fashion/I followed this small cluster of swirling tightly packed orbs that slowly drifted across the sky for about a mile or a half in my car until I got out of my vehicle where i observed them again for a few more mins until one broke off from the cluster going sideways then moving straight up into the sky stopping then turning Star-like bright & then disappearing/about less then a min later the remaining cluster of orbs just simply vanished before my eyes....
