Okay, I guess the bit you didn't know about her name, that part you had to ask about, is not significant - just the bit you did know. Obviously the walking on water has religious connotation, as does the woman's name, so I wonder if there is some connection there. Perhaps because you were being sarcastic to the people walking on water you have been wondering about religion recently, perhaps thinking it is rubbish? This is all assuming you connect people walking on water with something spiritual, Jesus or something - if you don't ever think about religion or know about Jesus then it may be something completely different. Even so, walking on water is a supernatural act whether it's religious or not.
I think because of your past relationship going wrong you may have been doubting the more spiritual side of life, love and so on - which is reflected in your sarcasm towards the walking on water people - and the arranged marriage to the 'holy light' is your subconscious's way of telling you that you need to be married (in the joining sense) more to spiritual thoughts in your life and not forget about them.
Second thought
There's also the possible connection between your relationship going wrong and your own self-doubts as to whether or not you can choose a partner on your own, that you are wondering if other people might be a better judge of who would be right for you. This doesn't mean it's true though, just that your dreaming mind is considering the possibility. I think this second thought is less likely than the first bit though, it may only apply if you never have spiritual thoughts and never think about holy spirits and religion.
