Strange urge upon awakening during early morning hours to find a colorful light orb the size of a softball outside my window.On 11/4/2015, around 3:00 AM I was awakened by an odd feeling and drawn to look outside my bedroom window. Once I looked out my window, what was seen has left me convinced, confused and wanting to know more about what it is exactly, that I saw. I live out on a cattle farm, and on that particular night the cattle were in the field from which I saw the UFO. It appeared to me as a very large, round light about the size of a softball, that was swirling with many different colors; purple, pink, red, green, orange that could have resembled a head lamp in its movements. The light floated in mid air for about 30 seconds as I watched it, then suddenly vanished moving to the east and appeared to enter the shadow/body of a single cow. This sounds highly unlikely and crazy at that, but I know what I have seen and no one can tell me that it was a drone or anything human. About two or three days after the sighting, while walking through the field, I came across the remains of a cow, missing its entire skull, clean cut- this could have been due to coyotes/birds of prey, etc., but for whatever the reason those two events to me seem as if they may be related in some strange way.
