What does this dream mean?

ok i have dreamed this about 4 times between the ages of 9 and 13.in the beginning i am a kinder-gardener and i am at my school during recess and robots/aliens(idk what they are i just know they werent human) start attacking the school.the kept on following me trying to kill me.then in the middle of the fight i end up in a dance club and i am 11 and the ground starts to shake.me and my whole family and the people in the club starts running out.outside we see rocket/bulletsts flying.well the rockets kept following up and trying to blow us up but we try to escape.we see the city panicing and we almost get hit we lay on the grown and they keep on missing us.then i end up on the free way with my sister and a blue man comes out of nowhere and stops our car with his bare hands.we try to get by and we try to run him over but we cant.so we run across the freeway and we end up in a swap meet.we go into a store and we try to hide.we see a stream/river going across the front of the store.then the man pops out of the water and try to kill us.we try to run but sharks come out of the water and help the man kill us and then right when we are going to die i always wake up.
