Reoccurring dream....what does it mean? I've had it for the last 4 months and have it up to 6 times a week?

I'm standing on a beach with pure white sand. I can hear the waves but they're muted. All of a sudden I'm in a white dress and I turn away from the sea and can see my whole family and friends stood there, but they're all fuzzy, like a badly taken picture. Next there's a loud buzzing noise and they're all fading away. The sea gets wilder and yet the volume is turned down. The sky is red and orange and purple. I feel afraid. I realise that I am on my own. I can't hear anything and I can't move. I feel enclosed and suffocated. The sea gets wilder again and I hear a really beautiful singing voice, but it's singing of something very familiar, I just can't figure out what it is. The fear increases. I still can't move. The waters suddenly lay still and a figure rises from the wild sea. And before I can have a look at the face properly, I wake up. There is always a sense of urgency to my dream, like I need to figure it out but I can't.
