Shape-shifting Cube like object in energy orb flying in a straight path trajectory

This is a photo taken in El cajon California by myself, this object was flying at jet speed in a very straight trajectory with no means of propulsion to the naked eye. This object appeared to start shape-shifting when I finally opened my phone it was almost too late. I got some great pictures though and everyone of them it looks like a different object. This is so crazy because I always look at the sky and it seemed very surreal but humbling. I have more photos and video but would like to keep these to myself and not include on this report. I feel like this is very paranormal for I was looking for this and it appeared.
