Breaking a Leg
Scholars have said that that seeing one's leg broken in a dream, if the dreamer intends to travel, may indicate the necessity of not undertaking this journey. If one sees their leg dislocated, it may suggest that their wife will fall ill. If one sees one leg longer than the other, it may indicate travel.
