First, the subconscious has six characteristics: 1. It has great energy: 2. It likes emotional information best. 3. If you don't know the truth, go straight. 4. Easily stimulated by images. 5. Poor memory, need strong stimulation or repeated stimulation. 6. When you are relaxed, you are most likely to enter the subconscious. Your brain function consists of consciousness and subconscious. Consciousness is actually the main consciousness. Your subconscious always listens to hints, and your subconscious completely controls your body functions, conditions and feelings. The function of the subconscious is also the instinct of self-defense. Your strongest instinct is to hint at your ability. In fact, psychiatrists, psychologists, plastic surgeons, massage practitioners, churches, etc. Are using the power of the subconscious. They induce and hypnotize you to believe in some kind of illusion. The so-called illusion here does not mean false things. For example, "it is said that a patient with tongue paralysis has lost the ability to speak, and various treatments have no effect." He told the patient that he had a new device to treat his illness. In fact, he just put a pocket oral thermometer in the patient's mouth, but the patient thought it was a special instrument that could cure his illness. A few minutes later, the patient actually shouted and his tongue was free. " This simple example is actually trying to say that the subconscious mind is actually a "machine". When encountering some problems or situations, its reaction speed is faster than that of the main consciousness. Here I want to make it clear that the "takeover" mentioned by the questioner is actually not taking over, but the subconscious mind has been leading the main consciousness. Only when individuals are alone, sometimes you feel that some things or situations are being taken over by your subconscious mind, but as I said just now, when answering the above, I personally think that this question involves a wide range and has many explanations. I may just come up with an explanation to answer your question. If your answer to me is not very clear, I suggest you look at the Collected Works of Dr. Murphy, the world authoritative subconscious psychology. After reading it, you should understand the feelings of the subconscious, and the subjective consciousness is very clear to everyone, so I won't explain it much. Maybe you will find a better and easier answer in his collection.
