Dreaming about cement means having concrete ideas and strong foundations. The many ideas you may have will combine into one powerful concrete idea. If you are currently working on a project, put it all together to arrive at a crystalized central idea.
Strong foundations are built from day 1 to the present depending on the focus of your work. In the waking hours, you will learn to put it together piece by piece. Once you have more than you need, the strong foundation will be complete. Pay attention to what you keep, and what you trim.
