Am I Going to Die in a Explosion?

Ok, so this isn't really a real-life story, but i had this dream...

So in my dream I was told i was going to die, that a bomb would hit me and i accepted it. I was just thinking about "Is there a real after world? I'll be a spirit." So i was counting in my head to 3. When i hit 3, there was a small pause and then i died... But i didn't wake up. I felt a sharp pain and i breathed heavily for a moment and the scenery changed INSTANTLY! Only a few people could see me. I was at my school, in the hallway and everything was black and white.

Some people say your dreams are related to your life... What do you think? Ok, yea, it wasn't a real life story it was my dream. But I'm kind of nervous because I have been having a lot of these types of dreams lately. : /
