Dream Analysis, Anyone?

I was sitting with a little blond girl on a train-like ride....kinda like those mini-roller coasters for young kids they have at the county fair, but the track was on the road. She could have been a little girl of my own. Her hair was very light and straight, but no longer than her ears. She was being disciplined by some older Indian man because she was not sitting down while the 'train' was moving. She was to stay in her seat while the train was moving. I said to her, "If you stand up before the train stops, we will have to ride it again until you can stay seated." I began to feel very very sad for the girl, because she was so innocent to the reasons we were asking her to curb her eagerness and enthusiasm. I continued to encourage her to stay put until the train reached the huge "Stop" sign that I could see ahead of us. I could feel the girl start as if to stand, but she would restrain herself. My hands must have been resting lightly on her shoulders. I did not restrain her, though. As the large stop sign drew nearer, I anticipated the feelings of relief and accomplishment she would have when she could get up and go to where her fancy took her. Those feelings were frustrated when our little train rolled past the stop sign and off a rather sudden end of the road....into the water. As we entered the water my concern was how the external intentions and signs deceived us. The girl could not learn the lesson of self discipline/restraint for safety's sake....she had just plunged into water and she did not know how to swim....she obeyed, but she was no longer safe. The stop sign did not mean that the train would stop. I expected the train to obey the sign, so the girl could learn, and make some sense of why I (or we, as the direction had first come from the older Indian man) wanted her to stay seated. Is the message here to not always trust the good intentions people have for our well-being, for they cannot control all the things that contribute to our well-being??
In the water, I felt quite calm. I felt safe. I held the little girl above the water and I sank underneath the surface. The older Indian man appeared and took the girl to safety. I do not think I remained underneath the water after the man took the girl. However, the purpose of the dream must have been served because the story and the scene dissolved away...
