From ancient times, humans have always been interested in strange sleeping events, especially dreams. Dreams are drawn in various ways. For example, a dream is interpreted psychologically as a subconscious image and feedback from the human brain neural processes. Mentally, it is described as information like God. It is worth noting that not only human beings can see their own dreams but also some animals (Wilkerson R. 2003). For example, the mouse sleeps almost as much as a human sleep; they do multiple stages of sleep from slow wave sleep to REM sleep (animals have complex dreams, 2001).
We can think about the scientific research of dreams in various ways. One way of investigating dreams is the study of the contents of dreams - themes, emotions, images, and events that occur and develop in dreams. Another aspect of dream research is the observation of the brain and physical activity as it happens. These two broad paths often overlap, scientific investigations explore both the content of the dream and the mechanism of the dream. Several of the latest and most brilliant developments in fantasy research are like this. Both ways to investigate dreams reveal the nature and purpose behind our very complicated and convincing dream.
For decades, research on dreams has led to research, research, and experimentation by scientists. The research thoroughly studied the causes and influences of our dreams. The University of California at Santa Cruz defines dreams as a way of thinking that occurs when a specific but minimal brain activity is in progress, such as while sleeping. At some point in life, everyone trying to experience a calm dream, you are consciously aware of your dreams in the state of your dreams. The more scientists study their dreams, we can find more information about ourselves and our brains.
The word "lucid dream" is a Dutch writer and a psychiatrist Frederik van Eeden made in the article of "Dream Study" in 1913. The explanation of the dreamer understands that their dreams are earlier than the actual term. Frederik Van Eeden has studied his personal dream since 1896. He wrote the most interesting things, and among all these dreams, what we now know is "a lucid dream." In all the data he gathered from his dreams, he created different names for each type of dream. He raises seven different dreams; early dreams, morbidity, ordinary dreams, brilliant dreams, devil-like generic dreams, and finally a cool dream. Frederick Van Eeden said that the seventh dream, somber dreams are the most interesting and the most valuable research. Eeden studied the lucid dream from January 20, 1898 to December 26, 1912.
