stars moving in the night sky

we were all sitting outside with a few neighbors when one of them noticed a strange star in the sky we all looked up and saw the star move thinking that it was an airplane. that's when the light or star stopped moving and then seperated and became two stars it paused for a moment and then went back together. after it went back together it vanished right before our eyes.
I was young and didn't really know what to think. my parents have always believed in ufo's and the such and I never have known what to believe I'm 40years old now and I still don't know what to think but my father asked that I report this and tell the story of what happened that night.
later that night, after I went to bed, I woke up and saw a bright light coming from outside. I just thought that it was early morning and went to use the restroom. but then we heard something that woke dad up and when we went outside our dog had pasted away. what was strange was that it looked like he had a broken neck..... I don't know just doing what I am asked hope this helps
