Dream of kids, puppies

I was inside a big house with other people I do not know who they are. Suddenly a despairing feeling aroused from within me and I was telling everyone present to evacuate and go into a room that was part of that house. As we were inside that room which was small compared to the house, it had one big long window with nothing to cover it and it was all the way up of the beggining of the wall. So outside of the house a flood was happening but there was no people just us, is like if we where at a ranch far away or something but the flood was hapoening with a poisonous chemical that looked like water and greenish at the same time and if it touched you it would decompensate you. Eventually I got all the kids out from that window and into a safe sirface and I was the last in that room with two puppies I do not know and a mans dead body which we accidentally killed by defending our own lifes from him. By then the chemical had enter the room and I was floating on an air matress almost touching the ceiling holding both puppies waiting for the chemical to destroy what was left of the room with me in the middle of it trying to survive with the two puppies.
