प्रश्न
Sometimes you remember a vivid picture of a dream you saw. What is the role of your eyes in this experience?
उत्तर
The brain sees the vivid picture of the dream through the eyes. Our eyes have actually never seen the vivid picture. This is an example of optical illusion. The area of dream is controlled by the cerebrum of the central nervous system. So sometime we can remember the vivid picture seen in the dream.
