Sleep and Dream

The brain needs to sleep to regenerate and while this process it dreams to reorganize data. The brain can shift into different stages when the person is asleep. The brain passes trough five different stages; these are called stage 1,2,3,4 and REM. In the REM period meaning rapid eye movement is where the brain does most of the dreaming. Scientist use people with REM disorder to help them understand this stage of sleep in the brain. These people brain does not turn off the connection of brain and muscle during their sleep making the act their dreams vividly. They have found that you could dream in any stage but REM is where the most vivid and real dreams are found. Scientists have also observed that REM dreams are typically more negative, the found that 3 out of every 4 dreams are negative. They have predicted this because the amygdule, the part that control emotions, is more active because the brain is more active as well. Deep sleep which is responsible by stages 3 and 4 help repair brain cell. REM sleep however organizes data or learns to act in a specific situation. The one who is responsible for the creation of dreams is the Parietal Lobe. Dreams are predicted to occur for many reasons. One is the remembering of thing we have seen or lived. Nightmares however also have their specific function; this is a form a survival. Nightmare help create situations and places that can be dangerous and it’s a drill or training of how to act. Traumatic events happen in the past can also be responsible for such dreams. Research concluded that lucid dreaming can be possible. Lucid dreaming is to become aware of the world while you are dreaming. This can be learned and can be a good training for you to become aware even when asleep.
