Dream dictionary: school bus dream meanings
(Carrier | Carrying weight | Burdens | Forbearance | Serving others) In a dream, a porter or a carrier represents a school bus driver who is entrusted with bringing the children to school, then taking them back home. Whatever appear- ance he shows in the dream, it will indicate the mental state of the school bus driver. A porter in a dream also represents someone who is carrying his own sins and burdens. To see oneself as a porter in a dream means doing penance. If a porter enters before a sick person in a dream, it means recovering from an illness. (Also see Tithe collector)
