You are worried that this will affect your present life, so you will be afraid and behave like a black cloth in your dream.
I don't know if the cloth covered you or floated down. If it is to protect you, it means that this matter will inevitably affect your future. If it floats on your head, it means that you may have the ability to resolve the shadow of the past.
I don't know how old you are, but this dream should be related to love or work. Face it, it may not be as bad as you think.
