Dreams are basically stories and images that our mind creates while we sleep. They can be vivid. They can make you feel happy, sad, or scared. And they may seem confusing or perfectly rational.
Scientists say the higher your I.Q. the more you dream.
Studies have looked into the importance of dreams to our health and well-being. In one study, researchers found out that some dreams may help our brains process our thoughts and the events of the day. Others may just be the result of normal brain activity and mean very little, if anything. Researchers are still trying to figure out exactly why we dream.
An average person has over 1,460 dreams a year which is about 4 dreams every night. As much as 95% of all dreams are quickly forgotten shortly after waking. According to one theory about why dreams so difficult to remember, the changes in the brain that occur during sleep do not support the information processing and storage needed for memory formation to take place.
Recently, scientists in Japan made a breakthrough in decoding the content of dreams. They used a technique called neural decoding—which involves brain scans and repeated questioning of study subjects—in order to identify visual content in dreams. The researchers were ultimately able to predict dreams' visual content based on brain activity with 75-80% accuracy.
