The summer of 1987 was the time the stars themselves came out to dance!

During what I recall as being a warm summer's night back in 1987, I chanced to gaze straight up into the clear (moonless?) sky as I sat chatting with my landlady on her back porch steps. Although there was a noteable diffusion of light across my field of vision due to nearby city streetlamps, the view of the night sky was such that countless stars could still be clearly identified. To my surprise, however, the field of motionless stars I expected to see was instead replaced by a field of 'moving' stars, meandering slowly about in a fashion much like tadpoles in a small pond. These objects replaced the stars, they did not obscure them. That is to say, I could not observe anything at all in my field of vision of the sky except the objects. There must have been 30 or more in that particular area of the sky. They had the same shape, size, color and brightness as the stars I fully expected to see. They did not exhibit any visible trails or emit any audible sound. I pointed out the phenomenon to my landlady and she observed them as well as I. We had the luxery of being able to watch the event for as long as we pleased: the objects were still moving when we retired inside for the night which was about an hour later. The next evening was almost identical in terms of viewing conditions. As I sat next to my landlady in the same location as the night before and roughly about the same time, we both observed a repeat performance of the event. A short while later, two friends came by to visit and observed the phenomenon with us. It scared me very much and I can only imagine the reaction of the witnesses with me, although they did not appear to be outwardly that concerned. To this day I cannot explain the event to my satisfaction. For those were the nights the stars themselves came out to dance!
