I think you may be trying to take the images too literally; it helps to keep in mind that your unconscious mind doesn't know what a church is, or a son/baby etc, or even what New Orleans is... it deals only in emotional images and tries to match up the feelings you may have for these images it sends you and what it (your unconscious) is trying to say. The subconscious isn't an all-knowing perfection of spiritual knowledge and will often get the wrong image matched up with the wrong feeling, but it will usually be something pretty close... if you don't manage to interpret the message (if there is one) your subconscious mind will try using other images that evoke similar emotions in you until you reach some kind of epiphany or new awareness in your life.
