How things works?

I once had a thought: what if we had to program sleep at some point in the future? How are we going to do it? are we able to? I enquired of one of my friends! How would you design a sleep if you had the chance...? (I'm hoping you're one of the unnamed readers) Is there anything you might suggest? The story does not come to an end with these questions. If everything slowed down, or if a pattern stopped reacting the way it usually does, it must be sleep, since when a human is sleeping, they stop reacting to their surroundings, or to any changes in their environment. If this is the case, we are not even close to so-called sleep programming. Because even in my dreams, I can't solve a basic mathematical series that calculates the sum of the nth term. BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT BUT I can go deep into space, but not too close to the sun or too far from the moon; all I know about the moon is a little part ...
