Dreams are the product of the subconscious mind, representing emotions that you didn't notice during the day, and released through dreams at night. Things and situations in dreams are signals of change, but they do not represent their true meaning in reality. For example, if your friend gives you a white sweater, it may be because you subconsciously think that your friend's demand for you has certain constraints on you (white sweater), or it may mean giving you a certain sense of security. This judgment depends entirely on your feelings and feelings in your dreams.
Only the emotions and feelings in the dream are consistent with your real life.
