Two Disc type objects of white colour were revolving around each otherOn saturday night,around 2130 hours, we were standing on the roof of our house,when one of us saw two lights in the sky that were revolving around each other.After a few revolutions they appeared to come down to us.The shadow of that object appeared in light,which means it was not an imaginary object.then we saw it again moving at the speed of light.Then it appeared to come near us and we ran towards our home.We heard the dogs barking at a very high intensity facing towards that object.It was a white light object with a disc type periphery.After a while we again went to the roof and for a few minutes we did not see the object but again after 15-20 minutes we saw both the lights revolving in a variable orbit and making to and fro motion towards each other,we became scared and rushed towards our rooms.
