Dream of mother

I am over a friend's house and i am sleepy. she tells me to go to a room up the stairs to the left. her brothers are watching a game on tv. i am on my way up the stairs and i almost get to the top untill the house starts to shake and things start to fall. i get scared and confused. my friend doesn't seemed to be affected by it. she told me why aren't you going up the stairs. i tell her there is an earthquake and she tells me don't worry that happens all the time. i look at her with a confused face and she walks pass me. on the top of the stairs her mother is there. she asks her daughter whats going on. she tells her nothing she just can;t get up the stairs. she says oh.
