Tornadoes or storms in dreams can represent impending threats coming in the dreamer’s life. Whether the clouds or swirling winds are light- or dark-colored can indicate the source and the strength of the forces on the horizon. Storms can represent a positive cleansing or a restructuring necessary if they are white or light-colored…or an attempt to destroy, if the dream seems dark and ominous.
If the color of the storm is light or bright, it refers to something God is bringing. If dark or muted, it is speaking about negative or destructive forces from powers of darkness.
