This is a 2-part dream, so I will post both in this thread.
I wake up in my normal apartment, in my normal bedroom, when suddenly my mom rushes in, telling me something along the lines of "They're setting off a nuke!" I'm dazed and completely oblivious to what's happening at the moment, but her words kick in. Not knowing this was a dream, I panic. Fast. Literally running around screaming. I decide to hide in the bathroom, which for some reason is at the far back of my house. After that, I hear an explosion and that part of the dream ends.

part II
I wake up again, this time, what looks like my hometown, only slightly ruined (things falling off of buildings, cracked windows, etc). I walk in the direction of what might still be my house, only to see it's still standing-- and not ruined either. Everything is exactly the way it was. The next part is a blur, but gladly so, otherwise I'd be here an hour explaining in detail everything that happened. And trust me, a lot happened. This dream went on through my whole 10 hour sleep, so it was fairly long.
