The ancients found the darkness a source of great fear, and so dreaming of darkness could be calling your attention to a fear you have that needs to be dealt with.

Darkness also hides one’s surroundings, and so darkness in a dream could indicate that you are “in the dark” about something, and need to find the truth.

If you walk through the darkness into the light, this is showing you that you will indeed find the truth, and success will come your way.

If a storm causes a bright day to suddenly turn into darkness, this is a warning not to get too complacent with your present circumstances, and to save for “a rainy day.”
