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.
