Dream of children

I had a dream that I was in a plane with my four children, nieces and nephews. we were crashing into an ocean. Once the plane was submerged in the water, I was able to unbuckle myself , holding my breathe under water, then walk to my children unbuckle them and lead them to an opening one by one. I was able to do the. Same for some nieces and nephews but wasn't able to get some of them out, I couldn't hold my breathe any longer. Then I swam to an opening and got out of the plane.
