It could also mean that theres self-doubt. Dreaming of having a heavy heart, without having any justification for it in real life, announces that there will be an unpleasant event, perhaps an accident of someone close, which could be a relative or a friend. Dreaming of other people in grief or distress and tribulations, announces that theres suffering and problems approaching that will affect the dreamers family and friends.
