Dream Of Town Folks Living Simply

This dream was about

So I saw some town folks who were living a simple life yet they seem content. It looks like some of them are living in a cabin. I saw a Boy and a Man, massaging the mud in a square hole but it's not too deep. Then, the two glanced at their back and a huge flood came rushing in and then the town was wiped. I, who's near the bed.. but for some reason it's outside. Then I saw the flood rushing in and I jumped in the bed with my brother and sister... And as the flood passed us by... My sister and brother got wipe away... And I was left alone.. Although, I'm an only child in real life, I still feel sad about it..
