Lights in the sky over south Jersey?

I’m in bridgeton New Jersey. This was on march 25th 2024 at around 10:45 at night. I thought at first that I saw a plane. I’m used to that. Then I saw another one too close. Then I saw three then four. In the end there were around 30 or 40 separate blinking lights, some in a triangular formation, sitting still, some kinda doing their own thing. I figure some kind of mass drone thing. I tried to take another video, but when I went to take another one they were all gone completely. They made no sound. No drone buzzing, no plane noise. I’m not a conspiracy guy, I just want to know why they were there. The lights were mostly red, it doesn’t come across in the video. The video looks like I’m stupid, but it was me trying to get all of them and they kept flashing everywhere and I couldn’t keep up. Anyway. According to everyone I’ve shown, they have better things to think about like the bachelor and not looking at the real sky.
