Why do you dream when you clearly feel not asleep?

I'm Xiaoyang 3548, and I'm glad to discuss my dream with you. As a well-known celebrity of Baidu, I think the person who can really interpret dreams should be the dreamer himself who interprets dreams by thousands of people. Tell me about my interpretation of dreams. According to modern theory, dreams are subconscious, and what the brain has not done is done by the cerebellum. Dreams are subjective experiences, images, sounds, thoughts or feelings imagined by people during sleep. Dreams are produced when people sleep, and brain cells also enter a state of relaxation and rest. However, some brain cells are not fully rested, and weak stimulation will cause their activities, thus triggering dreams. If it helps you a little, please click the answer above, thank you!
