There are usually two stages in dreaming. One is in the morning. When we are almost awake in the morning, our brains will think, so we will dream. At that time, many ideas were called dreams. Although we think we have been dreaming for a long time, it may actually be only a few seconds, dozens of seconds. In the wonderful part, the brain stimulation will be bigger and more exciting, and you will suddenly wake up or wake up faster. Dreaming in the middle of the night is because the quality of sleep is not good, there are too many thoughts in the brain, and the brain can't stop thinking. The brain can't get effective rest and is stimulated, so the body and brain will be completely awake, and people will be awake. Therefore, dreaming makes the brain think so many things. Every time I wake up from my dream, I will definitely feel sleepy and tired.
