Dreaming of Death of Loved One

I dreamt that my boyfriend passed away suddenly without warning, what does it mean? We’ve been together for 6+ years.
Dreaming of someone dying usually means that person is in for something new in life. He or she may face some big changes, or meet with an exciting new opportunity. So some say it is good to dream of death, as it is only a metaphorical dying of one aspect of that person’s life – and whatever change comes about is usually for the better. However, it is also advised that you should not tell the person about your dream, otherwise you may cause something unlucky to happen to the person.
