A giant is a person, animal, plant, or organization that is much larger than usual. The Bible describes giants as the offspring of fallen angels and mortal women.
Positive: Dreaming of a giant could symbolize the unlimited potential and overcoming ability God has given you. Seeing yourself or someone else as a giant can mean strength, power, and rank.
Negative: Seeing a giant in your dream could also represent an attack from the enemy, demons that have come to inhibit your progress, and immaturity or a lack of growth.
