There is no idiom "the tide turned over." There is a saying that "the tide turned," but it's not an idiom because you can figure out what it means by thinking. Tides "turn" when they shift from high tide to low tide - the currents either go toward the beach or away from it depending on what tide is coming up. People say "the tide turned" or "the tide will turn" to mean that situations in life are changing, just in the same way that the tides change.
