Hello Dan,
Thank you for sharing your dream with us. Please take everything that I share back to the Holy Spirit as He Alone gives the accurate interpretation.
I’m not sure when (recent or period of life) you had this dream but strictly from this dream alone the scripture that came to me was “I am the Light of the world” (John 8:12) and John 1:5. You can look up more scriptures of light and the darkness/world. The clothing suggest that you are walking in righteousness (remember that when it is all said and done, The Lord Jesus Christ is our Righteousness). As for your friend it may not be apparent from “externally” onlookers of his walk but he is a light in the darkness. This was a play-on-words. The colours (white and silver) are positive in the context of your dream.
Shalom!
