Hi MissDreamer. I'm sorry that no one has replied with a dream interp for you. I have been away for a long time and thought someone else would assume the editorship. In any case, I will try to help you with your dream.
As I always remind dreamers, all the dream symbols vary in meaning depending upon how they relate to each other and to the dreamer herself. You have to see the symbols within the context of the whole dream. Otherwise, it's as though you're trying to understand the definition of a single word when a word's meaning can be totally different within the rest of the sentence.
Dreaming about a little girl, in this dream at least, seems to represent a part of you. (You intuitively sensed that already.) There was a time when you attended your inner child, nurturing your inner needs.
But as time went on, you began to forget and neglect your child-like self, the part of you that is trusting, open, at peace. As life's stormy times ensued, your inner self felt unrest. Once patient, your inner self is crying out to be heard and nurtured once again.
At this time, you realize that you need to pay attention to your inner self. Interestingly, in your dream you say that she hasn't eaten in two days. This makes me wonder if you have neglected yourself due to a pairing of some kind. Are you in a relationship, for example?
You do understand the importance of honoring yourself--your pure spirit--as you say in your dream that the people who put you in charge are going to be mad and that you'll get in trouble with the law. The law of the universe demands that we love and care for ourselves or there will be dire consequences (not as a punishment but as a natural result of neglect).
The little girl (who is you) asks for a solitaire. How fascinating. Your inner self is asking for some solitary time. Solitude. Meditation. Personal reflection. Time with yourself. A solitaire is a diamond. When you spend some time alone (in solitude), you will bring out the brilliance of the shining diamond that is your soul.
She wants you to "engage" yourself in some personal, solitary time to nurture your inner "diamond" self.
This dream is a message from your higher self.
