It was around 20 to 30 minutes after midnight and i was watching the meteor shower. in the distance sky was flickering from the lightning as there was a thunder storm, time passed by, saw one meteor way up in the sky. after a few minutes clouds started coming from the south-west and as the sky was barely visible, from the thunder storm direction through the clouds i saw a fast moving object, in a shape of a glider, it looked as it was cloaked as i did not see it over the clear sky, but only when it flew over the clouds around 1 kilometre above, it did not emit any light or sound, the color was dark grey and flew very fast with a speed of a jet, it headed towards the direction of the wind south-west and lost sight in the darker clouds. the moment i saw this object i knew it was not man made or any optical illusion or light from the lightning, it was moving with no sound or light and after i saw it i started to shiver and feel unpleasent in my stomach as what i witnessed was the strangest and oddest thing ever for me.
