Early a.m. went out to smoke, noted blinking green and red lights moving towards house, craft suddenly moved north then south in a quick side-to-side motion with blinking green and red lights that were somewhat of a rectangular configuration. Craft slowed, hovered, glowed orange-red when stationary, then started moving again towards the west out over Lake Michigan.Viewing the object created an extremely uneasy feeling, went into the house and locked the doors. Woke mom up. Mom witnessed the craft from a distance very briefly, noting that the lights were configured in a square to rectangular shape. Lost sight of the object as it traveled towards the east.
