I dreamed that Dean and I drove to visit our friends the Josts and as we drove up, there was a small black Cadillac parked in their driveway. When we asked them about it, we discovered that it belonged to some other friends of theirs and it needed repaired.
Black
Black symbolizes the unknown, the unconscious, danger, mystery, darkness, death, mourning, rejection, hate or malice. The color invites you to delve deeper in your unconscious in order to gain a better understanding of yourself. It also signifies a lack of love and lack of support. More positively, black represents potential and possibilities. It is like a clean or blank slate. If the feeling in the dream is one of joy, then blackness could imply hidden spirituality and divine qualities.
I also dreamed that I was playing the trumpet.
Trumpet
To see or hear a trumpet in your dream, signifies some sort of warning or danger that you have found yourself in. It may be a way for your subconscious to get your attention.
Not sure any of that is real or makes any difference.
