What is the meaning in a dream of whirlpool

I am in my house, doing normal things and I keep hearing booms. I go outside at the last big boom and I see all my neighbors homes are destroyed and they're dead - the houses are in the ground - not even visible - it's like the earth has compacted them. My family and i have to leave very quickly with only our pajama's on. We get out but our house is destroyed. Then we're at a friends house who lives high on a bluff over a river. We hear another big boom and look at the river and it has a whirlpool in it that's getting bigger. My husband says we have to go and on the way out we see friends we haven't seen in decades outside looking for their dog - wasting time when we should be evacuating. I wake up and realize I need to make bug out backpacks for our family with all the necessities in it.

A water dam that is very thin on which i walk, waterfall and green fields,whirlpool and I fall down

My brother and I were on a ship heading for a whirlpool. I threw him off the ship and onto a platform, but he fell hard and seemed to be injured. Instead he grew and offered me a hand to safety.
