Recurring Dream? or Sign?

There I am. Walking. All alone in this huge field. The grass is above my ankles, and brown. The sky above me is orange. Pure orange. In the distance, there is a school. A red brick school building. In the middle of this field, surrounded by nothing. And then, I see that between the school and me, there is a single tree. A big, strong, very alive tree, in the midst of all the dead grass and darkness. As I get closer, I see her. A little girl of no more then four, swinging from a swing tied to a branch. She is all alone, yet smiling. And she doesn't seem to notice me. "What are you doing?" I ask. The little girl picks her head up, and looks at me, uneffected. "I'm watching them." she states, calmly. "Who?" I ask. "Them." she repeats, pointing up at the tree with an innocent laugh, like little girls do. And there they are. Preschool aged children, playing in this tree, happily. Childish laughter fills the air. Then, all of a sudden, it becomes night. In the blink of an eye. There is a sound in the distance. Then it comes into view. A school bus is barreling down the field, out of control, and full of preschool children. I watch in horror, unable to stop it, as the inevitable happens. The bus crashes into the tree. Flames shoot out everywhere, and turn the sky orange again. And then, it is gone. Everything goes black. And then, starts over. This time, I know what is coming. And I see the little girl, and ask what she is doing. She doesn't remember. Not me, or the accident. And the whiole scene repeats itself over and over.

I know I love children. And I want to help them. To help them not be afraid. To protect them. That is my calling. So, after years of trying to decide what to be when I grow up, I have found it.
