Sleep researchers study the dreaming mind in sleep laboratories. Electrodes are connected to the heads of volunteers. These electrodes are linked to computers that sense the bioelectric activity inside the brain, indicating the different areas of the brain that are active during different stages of sleep. Researchers also track patterns of "Rapid Eye Movements" (REM) that indicate active dreaming. The volunteers are awakened during specific stages of sleep so they can report whether they are dreaming or not, and can describe their dreams. Researchers also use brain scanning equipment to observe the activity within the brain. Note: scientists cannot see the actual dream images the way the dreamer does, but scientists can observe, measure and track the activity of the brain as dreams occur.
