Duke of Zhou-people came back from the dead.

As the saying goes, people can't be resurrected after death.

But people can often bring the dead back to life when they dream.

This is related to the dreamer's psychology.

Dead people often remind us,

We have an illusion,

If I do anything,

He or she will not die,

When the people we love die, we are not with them.

Didn't hear the last sentence he said to us,

Which means he's leaving,

Let's live a good life,

Will fill our hearts with regret,

Influenced by these psychology,

And form a subconscious,

People's dreams are a way of catharsis of the subconscious mind.

So dreams vent our nostalgia and regret for our loved ones.
