To dream of a power outage (a “blackout”) represents your feelings of powerlessness in real life.

There is some situation in which you felt unable to do anything.

If you walked a long way in the dark during this dream, there is hope of recovering something that you had given up for lost.

If you managed to get the power turned back on, or if you found your way to the light, you will conquer your obstacles and achieve great success.
