Ancient Japanese thought every sound they spoke (including both vowels and consonants) had meaning, and they called this philosophy, "Kotodama" meaning a spirit of language. They thought words had their own lives. They also learned to tell someone's fortune by characters and sounds of his/her name. I think the method came from ancient China. Today's dream had something to do with it.
dream: I was in a car talking to someone. I can't remember who that was, but it was a male. We were talking about names. He told me names containing the sound of "Ro" is not really good.
