Apron
A protective garment for working in a kitchen or shop — a layer worn so the clothes beneath stay clean.
An apron in a dream is the dream's image of a working layer put on so the rest of the clothing beneath stays clean. The apron is not a uniform; it is the practical garment of someone who handles food, paint, animals, or repair. The dream brings the apron when something in your life — a role of service, a piece of physical labour, a hands-on project — is being taken up in a way that requires an explicit gesture of preparation. An apron tied on at the start of the day is the dream affirming the assumed role. An apron found stained beyond use, with the underlayer also marked, is the dream noting that the protective layer failed and the harder cleaning is now the cleaning of the self rather than the cleaning of the apron.
