What Does It Mean To Dream Of Celestial Phenomenon?

I can still remember that I was six years old when I started to have dreams about different kind of celestial phenomenon. It was terrifying and alarming that I feel like it was going to happen in the future. It did not only happened once or twice, but it keep haunted me through my dreams as I grow old and up to the present time.
.
I have already proved and tested that more of my dreams were prophetic. Sometimes it happened few hours after I dreamed of it. Sometimes it happened few days, few weeks, few months or few years. As they said, "It is both a curse and a blessing."
.
Few weeks ago, my husband took me outside in the middle of the night and showed me some celestial spectacular, an Aurora Borealis. It was really awesome. I can't help but be reminded about those celestial phenomenon dreams that I always have. Then, few days after that, my husband took me outside again in the middle of the night, we lied down on the picnic mat in the middle of the basketball court, and there we were watching the amazing hundreds of meteor showers. Very wonderful! And once again, I was reminded of those celestial phenomenon dreams that I always have.
.
But those dreams that I had were far intense, scary and unexplainable. Intense, because it was universal-wide. Scary, because it feels like it was the end of the world. And unexplainable, because it was something unconceivable.
.
Although, I take careful note of my dreams, but I am not a person who consulted a book or something else for the interpreation of my dreams, because most of my dreams came true literally, while some of them I called "generical" (that's my version of between generic and general). Anyway, since this dreams really bothered me and out of curiousity, I tried looking through online dream interpretation, but to my dismay, none of them gave me answer.
.
Well, I am hoping that one of my reader here on my blog can give me interpretation of these dreams, celestial phenomenon. I really want to know why these dreams have been haunting me through years and years.
