A mirror's reflection can never tell you who you are. It's in the dark and deep silence that the voices of identity whisper their truths. Fear of the dark  is more a fear of your true self  which often resists the noise and the clamor of daylight. The journey between light and and dark takes you into the Self and away from the garish and false imagery that fools us about who we are, who we want to be. Darkness has its own blessings for those with the courage to brazen out the fear. Ultimately you bring gifts of awakening into the light.
