hello i would like to know.. everytime i stare up in the sky while lying.. I can see other stars waking or changing position sometimes one by one and each of them i'll wait for some more minutes, some going to the left some going down or diagonally... I'm very sure that it really change position and stay there as permanent position ..
The planets move in thhe sky from night to night..but you are describing something faster than that. Of course airplanes at high altitude do this--but I think what you are seeing are satellites. Thse move slowly through the stars, sometimes getting brighter or dimmer.
Hope that helps.
