Dreams are not made out of nothing! Think during the day and dream at night!
1 You want your boyfriend dead,
2, you are afraid of your boyfriend's death,
She came to see you and talk to you after she died, which shows that you know that he loves you very much.
But from the perspective of dream interpretation, dreaming that people around you die is a bad omen. You should say goodbye. You didn't dream about yourself, but you should be doomed.
