Last night I had an AWESOMELY VIVID DREAM. But the thing is that it scared the living shit out of me!

DREAM:
I find my self at school, doing what I normally do. It seemed like a perfectly normal day. After the final bell rung to signal that class was over, I left school and went home. Later that night I went out side because it was cold out and it felt nice. I saw a beautiful wide open sky and the stars. Next thing I noticed is that the sun was out (which was weird since it was night time) and it was flashing weird colors. I thought it was like a dying star at first but then there was a giant explosion far off into the distance and the shock wave from the explosion came closer and closer towards earth and I could feel my heart beating faster. I closed my eyes knowing that I would die any moment only to find that I was still alive. Everything covered in ash, I thought that I was the only person left on earth. I walked around confused at how this could be and I found my Uncle still alive under some rubble. The sky was pitch black and I could hardly see anything. Then I see the sun appear again except there are 2 and they are much smaller. The sky was still black and it was really hot outside. I noticed soon that they are not parts of the sun but meteors aiming straight for me. I got scared again but realized that at that exact time, I would rather be dead than alive. I braced for impact only to wake up at the moment of impact.

Just wondering but could someone interpret this for me. I always believed dreams had something to do with emotion or something since I interpret my own dreams sometimes but this one had me stumped.

P.S. I took melatonin last night if that could contribute to weird dreams.
