What does my dream mean?

I'm in my last hour cl,drawing,when the fire alarm goes off.Everyone panics and runs out the door,I try to get out as well,but I trip over someone's bag as I go down a row of seats.Once I get up I realise everyone wasn't there anymore and they shut the down behind them.I run to the to door,seeing smoke coming out of the cracks,and use my shirt to open it since I thought it'd be hot.When the door opens I see fire and smoke everywhere and can't see the exit,I try to blindly look for it and advoid the fire when I bump into some lockers and fall backwards onto the floor.Then as I lied there and began to lose consciousness from the lack of air,I heard something like a wushing sound(realiseing it was a fire extinguisher,)then someone helping me up then drag me out by the hand to the outside of the school.After I got some air back in my lungs,I look up at my rescuer and see that it's my crush.
