The ability to dream is produced by which body system?

• A. Immune
• B. Endocrine
• C. Nervous
• D. Digestive

Answer: (C)

Dreaming comes from the nervous system because dreams are produced by brain activity during sleep. During REM sleep, the brain is highly active and the cortex and limbic system generate the images, emotions, and stories we experience as dreams. The other systems—immune, digestive, and even hormones from the endocrine system—play roles in keeping us healthy or influencing sleep patterns, but they don’t create the dream experiences themselves. Hormones can affect when you sleep or how deeply you sleep, which can influence how often you dream, yet the actual dreaming process is a product of neural activity in the brain.
