The foot in a dream is a man's support in his world and his endeavor. The cutting off of the foot is a loss of wealth, a difficult journey, or the death of an animal. Walking barefoot indicates worry, fatigue, and deficiency in religion.

The foot indicates striving for good or evil. An increase in feet is an increase in travel, wealth, or strength. Whoever sees himself walking on one foot will lose half of his wealth or his partner.

The foot is interpreted as the parents. The right is the father, and the left is the mother. Whatever bad happens to them reflects on them. Washing the feet indicates the removal of worries and the righteousness of affairs.
