The content of dreams can show what you are thinking during the day or what you want subconsciously, but because reality always runs counter to people's wishes, people think that dreams and reality are opposite. However, dreams can stimulate the potential hidden in the mind and heart, so dreams can sometimes solve problems that can't be thought of during the day. I often dream of criminal techniques in mystery novels, which I never thought of when I was awake. What you dream should be what you hope or fear will happen, so dreams have no meaning, but if you have a sixth sense, dreams can come true.
