Strange Afterlife dream

I did write about this dream in my dream journal, but i could not write down the dream i had before this one.

Ok, from what i can remember i was being chased through this futuristic city by a group of men (I don't remember why they wanted to get me). Anyway, at one point i had to destroy something (i can't remember what it was though) with a missle launcher that launches nuclear missles. Even though i knew this would kill me i fired it towards this thing i needed to destroy and it killed me in the process.
After i died i woke up in my house, it was pretty much the same as my house in real life. I was apparently dead and was in the afterlife, so i decided to go flying around (i was not lucid, i think). I had problems staying in the air as i allways got pulled to the ground. After i finished flying around the house i went into my garden. Now the garden was pretty much the same as in real life, apart from one major difference. The trees and the fence's that are in my garden in real life were gone. At the bottom of my garden were three massive buildings that looked like the buildings you get in cities. I tried flying up to the buildings but i kept falling down to the ground before i could get to them. And then i woke up.
