What is the meaning in a dream of tank

TANKS ROLLING THRU IOWA

I was at a friend's house, and his parent's bed was in the middle of the house. next to the bed, some stairs lead to an underground animal room. the first room had fish tanks. a bed with fish tanks around it. but it is all crocodiles, sharks and piranhas. the friend threw food at us so that the crocodiles could eat us or the food. in the second room was a kid's play area with what looked like a black lion and a white lion, somehow I ended up in the play area. the entire place was deflating like a jumping castle and the cage to the lions were open as I exited the gate a lion was in front of me as I turned around it grabbed me on my shoulder. then it cut to me being on a highway trying to tell people there was a zombie attack happening. everyone is dying around me. and everything repeated again

A whale aquarium tank broke and flooded and I had to choose between saving my son and husband
