Sleeping and Dreaming

Sleep is important for physical and mental functioning. In fact, getting proper sleep is as critical as eating nutritious food. It helps you operate at your best. As you sleep, your brainwaves change when you enter various stages of the sleep cycle. Moreover, if you get adequate sleep, you should dream about five times a night. Although psychologists do not know for certain why we dream, they believe it is essential for the mind and the body.
