What's the Purpose

I am working with friends on a large scale project. We are installing physical apparatuses. There is part that needs to be installed very high in the air with minimal structure. It is a big risk, but it all seems worth it. There is another part close to the ground. It is not understood what the apparatus does or what its purpose is.

I wake and return to the dream multiple times. Each time more detailed,  but still a giant gap in the two parts and no idea why we are taking such large risks.

Notes: Is the gap the lack of intimacy in my life with all the effort I am making?
