Couple of odd white starlike objects

Gazing overhead into the night sky, good clear evening, firstly sighted a fast moving dull white object, too fast for aircraft, traveling in one direction E to W. Then shortly afterwards noticed at first what looked like a star overhead, but it had movement, almost zigzag like, moved one way then another with a short pause between each move, gave impression of something searching around it, too erratic for an aircraft, movements too instantaneous from one direction to next and not fluid like.
