Psychologists have discovered that human beings experience several different states of consciousness during the course of a day. For example, people have times when they are especially alert and times when they are awake but not alert, often called "daydreaming." Also, while people are asleep, they experience different stages of sleep, each characterized by different patterns of brain and bodily activity. In a multi-paragraph essay, discuss the different states of consciousness that you have experienced in the past 24 hours, including any periods when you were asleep, alert, or "daydreaming." Be sure to describe both the brain and bodily activity you experienced during each state of consciousness. Include information from class materials, readings, and research on states of consciousness to support your discussion.
