I dreamt of flying objects failing.?

last night i had a dream, that i was in school me and my friends looked up and saw a russian space shuttle flying but it failed in the air and flew into us at high speed but it kept constantly happening explosion after explosion death defying dodges then the next day in the dream i went back to school and this time only one shuttle was downed but then a transport aeroplane (jumbo) didnt take off right and somehow i dodged this giant wing casualties all over then i wake up... (all the time of the dream the sky was clear and sunny if that makes a difference) can anyone explain this dream?
