A Piece of Bread
Scholars have said that if one dreams of holding a piece of bread and eating it in a street or market, it may indicate that little of their life remains, and if the piece is thin, the matter is more urgent. However, if the piece of bread is on a dining table or plate, it may signify sustenance and livelihood.
