Dreams are generally called to be the flow of images, series of thoughts and sense that occurs in the human brain during sleep. They generally occur involuntarily while our body goes in the unconscious state. No one has till date fully understood about the function and structures of the dream. But they have been great topic of research for all the people. Mostly for the scientist. People also show philosophical and religious interest in the dream.
Dreams are supposed to be the series of visions, images, thoughts, actions that human beings have wanted to do or to be once in a lifetime. They are our brain imagination which can be real and which cannot be also. Even animals also dream. It is very hard to interpret why the people and animals dream. Some believes that some dreams are representatives of the peoples’ secret desires. Other believes that the dreams help to solve all the problem that are raised during the day. Researchers have said that dreams help to consolidate all the memories that the people have got and also helps to replenish the brain chemicals.
Till date, no clear theories have been found for the formation of dream. Sensory cortex of our brain is highly responsible for higher level of thinking. They are also responsible for the stimulation of the brain stem which triggers the rapid movements of eyes. Dream image is supposed to be formed in the brain stem and it is sent to sensory cortex.
Sensory cortex translates this image in to the long complex story which we give the name of Dream. This is how the dream is supposed to be formed in our mind.
