Functions of Dream

Help us to learn

Robert Stickgold, an Associate Professor of Psychiatry, made an experiment to test how much dreams can help learning. He had some students play a shape-fitting game called Tetris for a few hours and then go to sleep . Then they were dreaming of falling Tetris shapes. The consequence is so interesting, because the worst Tetris player had the most Tetris dreams and improved their game the most. According to this experiment, the researcher found one function of dream which is "dreaming may help use learn by organizing memories and ideas." Also, when we dream, our brains done many important tasks for us such as sorting through the day's experiences and deciding what to keep and what to forget.

Help us to deal with emotions

Dreams do not helping us learn by organizing memories and ideas, but also, but also helping use to deal with emotions. Most of people found that their ability of memory is improving more during midnight, because around the midnight, our brains are the most activity. During this time, our brain help us learn and organize memories. "When our brain sorts and builds memories, it replays emotional experiences from the day, without the urgency of the real event. This smooth out the emotions attached to the memory, making them feel less pressing when you wake. Also, dream are also safe place for the brain to "play act" different solutions to conflict that you faced during the day."
