1. Dreams are the manifestation of the subconscious mind: the source of dreams is actually the subconscious mind, and conscious desires will only produce dreams after being strengthened by similar desires in the subconscious mind, because subconscious desires are always active, and they will unite with conscious desires whenever they have the opportunity.
2. Dreams are the reflection of the subconscious: dreams are the reflection of the subconscious, because at night, consciousness is replaced by the subconscious. In dreams, people express their desires in real life in a hidden way, which is limited by the subconscious mind, so ordinary people can't express their true thoughts from dreams.
3. Dreams help to understand the subconscious: Dreams help to understand the subconscious. Through dream interpretation, people can get the information provided by the subconscious mind, help people find answers, promote the growth of the mind, and sort out the fragments of the mind. Dreams are a shortcut to the subconscious, which can help them understand their psychological state and whether their bodies deviate from their normal state.
4. Dream is a kind of mental activity caused by local brain tissue (cerebral cortex) not completely stopping exciting activities when people are sleeping. The content of a person's dream is related to the impression of life left by his conscious mind, but in dreams, the impression of life often becomes chaotic, so the content of dreams always presents a chaotic and illusory state, which is expressed in the form of imagination or illusion.
