What does it mean when you dream about a collar?

Collars represent confinement and restraint (e.g., to “collar” someone). They also indicate completing or finishing something, as in putting the collar on a garment. Collars often are an indication of control (e.g., prisoners) or a token of subservience (e.g., slaves). This kind of dream may well describe a frustrated work situation or a confining relationship.

Collar

 

a ring or similar device that holds a shaft in some position relative to a base for processing established during installation, such as an end or middle bearing of a transmission. Collars are fastened to the shaft on both sides of a bearing to prevent endwise motion. They also may be used in the throw-out of a friction clutch to maintain the proper release distance or in the feed mechanism of a drill for use in drilling blind holes to a specified depth. Collars are made of steel or pig iron.
