One large round disc. bright golden gleaming GORGEOUS OBJECT about 50 to 100 ft in diameter. It moved so rapidly. completely silent and smoothly no hint of what type of power moved it. No windows or doors such as is familiar to me but obviously I was being observed for several minutes. I had awakened at 3:00 am or so, fully awake and walked to the living room and looked out across Lake Michigan from the four foot sliding glass door. On the horizon I saw a light and thought it must have been on a ship out there. In 3 seconds it was about 100 ft. up, perhaps 20 t0 50 feet over the water from the shore. It must have had powerful type vision to know I was there. I didn't have the courage to go out on the deck, but wish i could have put an object out there to see if it would be picked up and taken into the ship or if they would have left something in its place. After a fw minutes, it took off in a stunning arc, silently and rapidly over the roof and treetops and disapeared immediately.
