Black Tornado

I'm running around looking for my sister. I have a canvas backpack full of clothes with a maroon and blue jumper hanging out. A big black tornado is coming I can see it. I go down this stair elevator thing, thinking I'm going into a basement but its actually an airport operation centre. We are all watching this huge tornado through these glass Windows but then it starts to dissipate into nothing. I then leave looking for a toilet. I find one, sit down and forget to shut the door. Some girl walks in an I slam my door shut and she laughs. Then I wake.
