If you could show a causal link between the mood of the ocean and the lunar cycle then I might concede that it could affect people's moods. However, last I looked the ocean didnt have a mood. Another approach might be to show that movement of liquid in a brain altered moods and therefore and that anything that moved liquids caused affected moods but I havent seen that evidence shown here.
