In November 2012, i went to the terrace of my building and i just slept over there and was looking at the sky. In 10 to 15 minutes i saw 7 boomerang shaped yellow colored beams with no shine. Means it wasn't glowing.I instantly got up.I was feeling very excited and pretty happy as i am always fond of mysterious stuff.Then i tried to take a photograph by my camera.But at that time it was gone very far from me.So i got fail to take any photograph.It traveled from North to South.But i only saw that 7 beams.I did not saw any edges.That thing traveled very swiftly with no noise and anything.Then after 30 to 40 minutes i lost sight of the object.Then i went to the home.I told everything to my parents.As expected they did not trust me.
