In general: If the dreaming is occupied in his dream with the construction of machines, this refers to his technical and inventive abilities. He is able to create a structure which promotes him and makes easier to him the life. If a dream acts, for example, from road construction machines, the dreaming recognises that he must pay attention to the means which promote him on his way better. Psychologically: Mechanical engineering in the dream symbolises that the dreaming with technical and mechanical aid can tap forces which are not ordinarily available to him. If he constructs machines in the dream, this is a tip to his ability to control forces outside his itself. He is able to use these forces to his own advantage. Spiritually: At the spiritual level the mechanical engineering symbolises in the dream that the dreaming has accepted the rule about his internal forces and properly brings them to the application.
