What is life?

I dreamed of my late second uncle last night. He was still in healthy condition in the dream.
He was a pagan. He did not believe that spirits will ultimately go to either heaven or hell. Where would he go then? Where is his spirit now?
I heard from my family that my second aunt starts working now. I understand how she feels. She would rather working instead of staying alone in the house. Those heart-breaking memories would certainly kill her. What is her aim of living now? She depended totally on my second uncle before this. Their children are all grown-ups and live in different places. She is all by her own now.
What is life actually? Growing up, then working, then dying? Is that all about life?
