gosh, you guys are makin' me blush :d
i have to admit, i'm not my usual sparkling self right now, still worried about emma
but, i'll take a preliminary stab at this - currently at work so i don't have one book that i need, but i'll come back later to fill in the gaps...
here's the highpoints of focus - dark city streets, hospital, children, the person chasing you.
first, you'll have to think about why it's your ex-husband chasing you in the dream - what does he represent? remember, the people who are causing us harm (strange how it's always family or people who used to be family) are reflections of ourselves. it's usually because there is something about us or in us that it causing conflicting feelings that need to be resolved.
hospitals represent safety. although, for nurses it may represent more of a grander sense of security - afterall, that's where we make our income.
children represent our pure selves, our innocence, our naked self.
on the surface, i would say this dream is confirming something you may already know - your sense of self and spirituality, you're walk with god, so to speak, is coming into it's full fruition. perhaps the importance of knowing god's word, the scriptures, is how you have come to knowing your spiritual self.
"....i was lost, but now i'm found..."
comes to mind. further, in your dream, the hospital may represent heaven or your feeling of achieving spiritual fulfillment. it's my guess or suspicion, that your ex-husband hampered your growth in this aspect of your life, and now you feel you have found the tools to overcome past obstacles.
this dream, is one of celebration and confirmation. anytime we are able to get away from that which is causing us fear means that we have comes to a decision, reached a milestone, or have overcome that which has hampered us in some way. the key is to recognize what your subconscious is telling you to celebrate!
