Tea as a symbol suggests spiritual refreshment based on a reverence for nature and the creation of a perfect moment in time. The Japanese tea ceremony suggests a unique way of caring for and nurturing someone as does afternoon tea, each having their own rituals associated with them. Dreaming of teacups in particular links with our need to know the future (reading tea leaves). A tea break in a work environment suggests a need for rest and relaxation from concentration. It will depend on whether the dream is about tea as a commercial commodity, or a social occasion. On a practical level, tea as a commodity represents a unit of exchange, whereas the social occasion and the ceremonies associated with this suggests inter-communication and the gift of our time.
