- No, because rods and cones only convert light energy into electrical signals.

- No, because rods and cones never produce electrical signals.

- Yes, because the rods and cones are reproducing images that are then sent to the brain.

When we dream, our remains closed and no light is able to enter the eye as a result of which the rods and cones do not send the signals to the brain.
