3 triangular shaped crafts, dark, silent, no lights, very fast, in formation

We were walking a friend out to her car, and stuck around the parking lot to catch a meteor from the Orionids Shower in the perfectly clear sky, and with already looking up, we simultaneously saw 3 very dark, almost a dark grey steel like arrowhead shaped crafts flying extremely close together, moving south, completely quiet, fairly low overhead, and they didn’t waver-at first I thought they were large birds migrating but as they got closer, I quickly realized they were anything but. I have been witnessing nightly drones, of several shapes, sizes, and light arrangements, this was nothing like that. I have even been told I am paranoid, because they have “followed” me. I assumed they were the local sheriffs facial recognition drones or something because our development is smack center of a recently sold golf course, and the county now owns it and for the time being, it’s a park. My husband was holding my binoculars, as he had been looking at constellations and such, and was in such awe, they were in his left hand, and he had pulled them away from his face, his arms in the air wondering what the hell is that? I’m staring as these crafts smoothly and with great speed fly overhead and I see the binoculars and grab them and try to get a better shot and they were over the roof. I ran back about 15-20 feet to see them and they were gone. They were so low, our 2 story condo roof, even stepping back, I couldn’t catch a glimpse again. I was completely freaked out, repeatedly saying, “What was that?? What the hell was that?” No lights? Perfectly straight flight pattern traveling so close together? They were darker than the night sky and I’m sure with light pollution we were able to see them. Quite an experience!
