Dream about black glass is a metaphor for your identity and sense of security. Your initial assumptions were completely opposite of what you thought. You need to be more of a sport. Your dream is about your independence and autonomy. You feel you are being prevented from doing something that you really want.
Black glass dream is a portent for responsibilities and expectations. You need to manage your time better and plot out your goals in a more deliberate manner. Life may be passing you by if you do not participate in it. This is an omen for the union of your feminine and masculine side. You need to add more color and joy to your life.
If you dreamt about black glass:
You’re going to get it all today. You may not feel especially powerful, and in fact there may be those who try to make you feel incompetent. Realize that this is a passing trend and you will soon bounce back to your true self. Open up a little more than usual and let more light into your life.
