Earth destroyed by a force from space

I can only remember the lucid part of my very long string of dreams last night. I told myself I was going to go to the moon for expedition, but if not I'd try some tasks. I woke up and got a quick snack (a finger full of almond butter and a bite of potato salad) and went into this dream...

I'm laying in bed in a wooden house and a large silver teddy bear attacks me. I realize I have fallen asleep and my fear dissolves along with the teddy bear and the paralysis. I stand up and decide I'm going to fly away from the darkened room to clear my thoughts. I try to fly, but end up projected through a long thin tunnel. I can only see seemingly never ending wooden walls and a smal opening way off in the distance. I close my eyes and the motion stops. I'm standing on a platform way up in the hills and I can see the lights of a city in the distance, gradually getting sparser as I scan closer to the large platform. I try to fly like I normally do but don't feel I have the usual amount of control. I close my eyes and decide to mix it up a bit by thinking "Rocket boot activate!" (I think I read that someone flies in that manner on this forum and thought it might be cool to try) I begin my rapid ascent as the rocket boot blast me into the sky. They are super fast and very responsive. I think about falling for a moment and feel the g's in my stomach as I begin to fall rapidly back to earth. I begin to look at my hands and refocus, because I can't really see much. When I do I notice the background come alive behind them, but when I take them away it still feelslike someone has turned the lights way down on. I decide to float for a moment, bobbing awkwardly in the air way above the ground and remember what it is I wanted to do. I felt like I was almost there, but couldn't remember. I tried to remember other tasks but could not. I reactivated my rockets and blasted into space. It is dark behind me and a mass of darkness sprinkled with light below me. Then the pillars of flame begin. first one below me to the right, then another, then a few more. I realize they are meteorites, and that the earth is passing through a belt of small meteors. Then I begin to see the fires on the ground illuminate the massive darkened sphere. I am floating in orbit on the dark side of earth watching as meteorites large enough to impact the earth bombard its' surface. I begin to think I am in control of the assault and witnessing a future apocalypse. As I think this, a very large mass, which I assume is an asteroid falls to earth, creating a collosal column of flame, followed by a brilliant explosion, illuminating the dust and debris clouding the atmosphere of the once blue planet...
Don't remember anything before or after, but I wonder why I couldn't see behind me, and why so many small objects actually made it to the surface before 'the big one' hit. I think maybe it was an i assault from just outside of our orbit, NOT space debris.
