The wing in a dream is a son, wealth, or authority. Whoever sees that he has two wings and flies with them will gain authority and travel. Plucking the wing indicates the loss of wealth or dismissal from a position.

The wing indicates adornment and strength. Whoever sees himself flying with two wings will be blessed with two sons.

The wing is interpreted as wealth and a son. The strength of the wing is the son's strength, and its weakness is his weakness.
