Interesting, I would keep doing research if I were you. I think you have a natural gift.
As for the dream, have you ever tried to look at it as if each part represents a aspect of you? Just a suggestion but in one method of dream interpretation that I have sometimes found useful that is what you would do. For example, maybe the death of the older sister when she was young represents a part of you that died at a young age? I know you said that's because of a miscarriage but it's just a thought. Can't think of what about you the moon would represent. If you used this method it's really something that would need to be figured out on your own. Sometimes it's good to look for information reading about dreams but always remember it's your mind! The messages that get sent to you may not be shown the same ways someone else gets them. Trust yourself over any reading you do.
