Hello; i am new here so i just came accross your dream. I do dream interpretations so if i may, i will explain your dream to you. I have 45 yrs. exp, however i truly do not wish to step on any toes.
So as for the singing in your dream, It represents happiness, harmony and joy in some situation or relationship. You are uplifting others with your positive attitude and cheerful disposition. Do not be afraid to communicate and express your feelings. The joy you are feeling in your dream, again denotes harmony amongst friends and loved ones. The peace and tranquility you are feeling in your dream indicates an end or a resolution to an emotional issue or inner conflict. It may signal an end to a cycle and the pause before the beginning of a new endeavor. It also suggests that you have reached a new level of calmness and stability. Remember you do not have to be loved to love. Show your emotions and grow in spirituality.
Stay in the light, Grizz
