2. Dreams make you re-understand the truth you already know, or remind you of it. If the spiritual world is understood as the inner truth and religion is understood as the content that allows people to reconnect with their own origins, then the religious image will help improve people's cognition. There are various religious images in the world, but their existence cannot be expressed in any other way. It means that the spiritual world is an independent existence in life, just like the body and mind.
