Who can explain the meaning of my dream?
In my experience (20 years+), your dream is representative of your desires for this woman (rain falling indicates deep feelings and emotions). Her child running towards you seems to suggest that you do have deep respect for both of them, and that you view her as someone you want in your life long term. Seeing the children of potential partners in a positive way in dreams indicates this. It is not a premonition of the future, simply your mind working through your feelings and emotions, and possibly trying to give you a nudge in the right direction. I believe you also may feel paternal feelings towards her children which is part of your deep feelings for this woman.
