When I close my eyes and listen to music, I see colors. My ophthalmologist has no clue as to why this occurs. He has never heard of such a thing or had a patient who has mentioned anything like this to him. The fact that this occurs with me made this meditation so easy for me. Color breathing really worked for me. My living room became the most glorious, beautiful green with my exhales. Very calming and now I am off to sleep.
