We all have dreams, but few of us know why. We spend about a third of our lives asleep, and it turns out that dreams are the result of the same neurological processes as our waking hours. But why? Why do we dream? And what can they tell us about ourselves?
The purpose of dreaming is still hotly debated among scientists today; however one recent hypothesis surmises that human dreaming is an evolutionary adaptation that allows our brains to learn, store, and process all the information we experience during waking hours. This means if this hypothesis were correct, then both your conscious goals (like learning how to ski) and unconscious goals (like consolidating memories) happen at night when you're asleep.
When we are in a very deep sleep we dream.It is believed that when our eyes moves rapidly in sleep (REM,Rapid Eye Movement) we dream the most.Our dream are inter related with our thoughts,emotions,day to day activity etc.Dream proves that even when we are asleep,our brain is active.A very interesting fact about dreaming is “in the total life span,a human spends an average of six years in dreaming.”And also when we dream our body is still,it doesn’t move.
