Have you ever seen fish and snake sleep but they do not close their eyes ?
Do you know the answer ?

Snake and fish sleep with their eyes open, because they do not have eyelids; they cannot close their eyes.
Men and women have eyelids. We cannot sleep with our eyes open.
When we become tired, our eyelids become heavy. They close over our eyes, and then we fall asleep. Most animals also fall asleep in this way.
