3 lights in formation, odd movements

I had my phone out taking pictures of some cool storm clouds. Then saw the first two lights, the third quickly joined the other two lights in a triangle formation. The third light to join was moving erratically amongst the other two in a somewhat horizontal pattern. Once stablish the top right (top right in the formation) started flashing, as if it was signaling the other lights. After a few flashes the first light flew off, above (I think) the mountain range and disappeared. Then the light started flashing in a different sequence (seemed like the flashes slowed down) and seemed to be signaling to the bottom light, which then proceeded to fall towards the ground. (Keep in mind, these lights were above the mountain range to start) while the second light was falling it was falling IN FRONT of the mountain, you can see the light rotating while it’s moving towards the ground, Before it disappeared into nothingness.. Lastly- if you pay attention closely you can clearly see the 2nd light seems to be skipping (disappearing then quickly re-appearing in a further away position!). I have other footage of other things I’ve seen during different times and of different “objects “
Not to sound crazy but I’ve been seeing things like this in the sky since I was a kid! And have been able to tell people when we’d be seeing something odd in the sky!
