3 metallic ball round shaped objects all with spikes sticking out of them, glowing white very very brightly.

I was walking through a local forest with my dog. Then i saw these three glowing round objects north east to me about 50 meters high. I stared at these lights in disbelief for about 5 minutes until they started to move slowly TOWARDS ME. As they moved closer i could see the shape and that they were definitely some kind of silver metal. They got to about 15 meters away from me at about 10 meters high, my dog started barking as they made a slight humming noise at this point I shat myself (scared of being abducted), turned around and sprinted to my car with my dog. I sat in my car for about 15 minutes then i returned to the same place with my phone just to see that it disappeared.
