Four ways to read it
Each reading below comes from a named tradition and a cited source, so you can see where it came from and decide what fits your dream.
Freud
Freud might read the workings of a machine as an image of the body or its drives, so the mechanic who repairs it may stand for an effort to restore something that has faltered within. He would ask what part of the self feels in need of repair.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung might see a mechanic as a figure who restores function and order, one who understands how the parts fit and move together. The figure can embody the practical, mending side of the self.

Continuity ties a mechanic to real situations that have broken down or need fixing, in your routines, your body, or a relationship. The figure often appears when something is not working and you want it set right.
Continuity hypothesis (our summary).Mythological
The skilled smith and maker who mends and forges runs through myth as the figure who keeps the works of gods and heroes in repair. The figure tends to embody craft and the restoring of what is broken.
