I cannot sleep. Because of this I think of various things. Perhaps in thinking, I will find something that will cause sleep. I am not sure, was it before I fell asleep that I remembered this? Or while I was sleeping?
What happens to the eyes when one sleeps? Do eyes really remain in place? Do they roll around while we sleep? It is so dark. What if we are not actually sleeping? Perhaps our eyes leave while we are sleeping. They may go and take a break. They may figure we will not wake up and leave all night.
If our eyeballs can come out on their own, where do they go? Maybe while all the people sleep, they travel across the universe to where they were born. Or they go and create more eyeballs. It’s while we sleep that they flee. Through the nose. Or the mouth. That might be why we have bad tastes in our mouth."
