We will all live forever.
After death, our bodies will disappear from this world, and our souls will go from here to another world, the world of God. The "man" here can be directly called God. They are omnipotent and can even live forever. However, God has no emotions. They only have themselves. While dreaming, it suddenly felt lonely...
When you wake up, you are in a dream.
Intention: To coax the majority of netizens to live in the present and let themselves be themselves.
