Bright and wavy

One by one the objects came and went right above us. Some going in diagonal directions. There would be a few that would flash a brighter light then go back to its normal brightness and fly along in the sky. Some would travel fast and some slower than others. Every minutes or so another would come. It lasted about 15 minutes. There was this one particular one, it was bright and a shape of a circle, when it came closer to us it flashed its lights real bright then left. It was moving in a wavy motion as well. Zig zag like. I do have video proof of this object I am talking about.
