bright light half the size of moon with 2 smaller lights

I was 16 years old and was sitting in our camp with my dad and my grandparents.  It was a cold clear night and we were talking about the time my dad and I were spot-lighting deer and I held the spotlight on a deer while my dad slowly walked up to it and he actually pet the deer.  They all coaxed me to go out in the camp yard and see if I could walk up on a deer so I got my coat on and with flashlight in hand went outside.  
I saw a deer right away, but I was distracted from the deer by a bright light in the sky which was about half the size of the full moon which was also very bright.  I tried to tell myself it was just the north star and looked at the deer again.  I was distracted again because the light seemed to get brighter and dimmer like a twinkling star.  
As I looked at it again for about the third time two smaller lights shot out the side of it and stayed stationary on the same plane in the sky evenly spaced apart.  
Suddenly, the big light appeared to shoot straight up followed by the two smaller lights one at a time and very quickly, as if the ufo’s spotted me holding the flashlight on the ground.  They disappeared so fast, I immediately ran back inside and told my dad and grandparents what I saw.  They started laughing and I nearly thought I must have lost my mind because they didn’t believe me, but I knew what I saw and ever since have always been interested in sightings to see if anyone else has  seen anything similar.
Witness indicates that the date of the sighting is approximate.  PD
