...well, this seemed more like a nightmare than a dream, but I wonder if anyone has an interpretation of what my dream might mean?

I started off walking through a town that was unfamiliar to me and it seemed a little chaotic. The electricity had been out in the entire town. Everyone was outside talking amongst each other saying "Today is the day the world is supposed to end" And I thought to myself "It's the year 2012 and this is the time that everyone thinks the world's going to end" but I denied it and said that everyone was just paranoid. So I walked inside this convention center. It was a huge building with lots of people inside. and I took a seat in the very front row. I was there to enter my artwork in a competition. Just then, I turned around, and my mother and my boyfriend were coming through the doors of the build and they looked horrified. Just then, the ground began to shake violently and people began to scream. I pictured an asteroid hitting the earth in my mind. I remember getting up and running to my boyfriend. I hugged him tightly with one arm, and I grabbed my mothers hand with my other arm. My boyfriend said to me "The world is coming to an end and I had to be with you one last time" Then the building started to crumble to the ground, and a giant flood began to take over everyone. The sky was an unusual color and the sun was so bright. It was red and looked alot closer to the earth. People were screaming and crying, and I saw people drowning. My mother got swept away. I clung to my boyfriend and we tried to keep our heads above water. I was screaming and crying and I felt tremendous fear. I remember screaming "I don't want to die! I still have so much to do, so much to live for" There was this raft like structure floating in the water in the distance and lots of people were trying to climb on top it. Just then, an angel decended down from the sky. It's wings were incredibly long. The angel's robes were all white and flowing, and it had a very bright glow to it. It looked straight at me with no expression, and didnt say anything. I didnt feel fear anymore. I felt calm and at peace. I dont remember dying in this dream, but everything felt so real. Does anyone have any idea what my dream might signify?
