8-10 objects moving at incredible speeds in and out of cloud cover

Visited the area with a friend and we were sitting in my car near the boat launch. It was approximately 2:30am, very windy, with low level clouds and fog. Three is no natural light source, so it was pitch dark. I noticed the objects first.There was approximately 8-10 craft (?) which appeared directly within our line of sight. There movements were erratic, and they seemed to be darting in and out of the cloud cover, side to side and up and down. Most were an intense electric blue color. A few appeared dark red. My companion thought they may be drones. These were no drones. The speed with which they moved was frightening. Their ability to instantly stop, or change direction,made me think I was hallucinating. They did not emit any sounds at all. Completely silent. We both got the distinct impression that they knew we were there and watching. While I didn't feel threatened, I did feel as though I was interrupting something. Twice, one of them would burst through the bottom of the cloud cover,stop, tilt slightly forward and a a bright white light would sweep rapidly side to side. It would briefly pause as it illuminated my vehicle. I was to dumbfounded to react. But fear was starting to set in. When the second object did the same 2 minutes later, we quickly left. I returned to Briery the next summer with a group of 5 friends to do some night fishing. That night was clear with a half moon visible. Something in the north eastern sky caught my eye and I looked up. And there they were. The same objects. They were further away this time, but making the same side to side and up and down movements. All five people saw the and could not stop watching. Again we all sensed they knew we were there and watching. And again, on occasion, one of them would dart forward toward where we were, and the "scanning light" would beam our way. I don't know what these craft were, where they are from, what they wanted, I do know that to my knowledge there are currently no aircraft that could come close to matching the speed and agility of the craft I saw those 2 nights.
