I was looking out my window and saw a bright white sphere shaped object traveling somewhat fast enough to catch my attention. I thought it was a plane but in my area, they usually pass by in the opposite direction. I decided it was a bird since it was white but then the altitude did not match. Then the object, stopped mid air. I jumped closer to the window to see if I could get a better look and 3 more objects followed the first one. All had same shape, size and color. They positioned themselves in front of the first, in a straight line, also fixating their position mid air. Following that, the original object in a circular motion, moved in front of them. Then, copying what the first one did, they also, in a circular motion, moved in front of the first object. After this, they continued (all 4 objects) to move in a spiraling motion, like a carousel. Always moving N , and about 50 seconds after all of this happened, they went behind a cloud. I was ready to snap a picture if they emerged from behind the cloud but they never did.
