it means that teachers help us reach our dreams through giving us knowledge. they feed us with values and knowledge, and they inspire us in chasing our dreams. they are the bridges of our future because they are doing their best to make us have interest in being better and when they know it's time for us to be independent, they inspire us to also inpire other people through creating our dreams in our image and to help other people too. they encourage us to be a bridge also to other people's dreams and to take part in helping build the new generation to come a better future.
