Psychological explanation of dreams?

Dreaming is a normal and indispensable physiological and psychological phenomenon of human body. Dreams exist because of sleep. Our sleep generally has five stages. The first stage is a shallow sleep, which is easy to wake up. The second stage is deeper, and the third and fourth stages represent our deepest sleep. This process takes about 90 minutes, that is, after four stages, our sleep enters the fifth stage of rapid eye movement sleep, and our sleep all night is the cycle of these five stages until we wake up. Rapid eye movement sleep can lead to dreaming.

Everyone dreams, the difference is whether they remember it or not. Researchers found that fetuses and babies spend most of their sleep dreaming. Moreover, women remember more dreams than men, which is more obvious when the parties are under pressure. We want to recall our dreams. When we wake up just after the dream, we have an 80% chance to remember the content of the dream, and when we wake up at other times, we have a 30% chance to recall the content of the dream. Dreams at this time are often fragments of ideas and thoughts, not visual scenes or sounds. Compared with sudden awakening, slow and gradual awakening makes people recall their dreams more easily.
