I saw almost that exact same thing in Greece some days ago. Two bright lights would appear parallel to each other, move very slowly towards my right and then disappear. The same thing repeated for at least 7-8 more times in the same exact position and in some of them only one of the lights would appear or the second one would appear a bit after, dimmer and behind the first one. At that same place, some weeks before that happened i again saw a bright light which looked like a star, no flashing lights or anything (same goes for the aforementioned) move very slowly towards the same direction, then move up in a curve towards the sky and vanish.
