unfortunately i don't recall much but this is what i remember :
me, my mom and 2 of my brothers are outside some type of hospital. there is no emergency but we're just there. the weather is really dark, like, the sky is covered in clouds and it's really dark with a bit of wind.
we go to the top of the building only for my mother to tell us that we have to go back down and to another building. even at that other building, my mother tells us to go to the roof. and we do. once there we see that there is a kind of plank between this building and another building. my mom tells my younger brother to cross over to the next building using the plank. than we both start talking and when we look back we see that instead of K, my youngest brother S is crossing over. he is walking fine for a moment but than suddenly loses his balance and falls down. the fall to the bottom is quite long as the building is really tall but when he does hit groend i see a puddle of blood forming around him. i run down and in panic but see that he's still alive. i pick him up and realize that i'm covered in blood too. my mom is just behind me. she tells me to carry him to the hospital and i do. but when i get there, i wake up.
