Two things were there since the earth and search began, but at that time online was a thing that was working from thinking.

However, it still works; as the human brain connects from anywhere to anywhere even faster than the internet, directly about thinking about something to anything.

We can say two worlds exist there in the universe offline & online and there's nothing in between them.

I think whether we are sleeping or we are awake we are online as the brain never sleeps, as per reports brain is the most active part of the body during sleep.

Brazil Says: There are pronounced changes in the electrical activity of the brain during sleep, which the evidence suggests is a result of the brain’s trillions of nerve cells rewiring themselves.

This rewiring, which happens during deep, slow-wave sleep, is how we process and are thus able to retain new information we may have learned throughout the day.

“Your brain is making a map of the information”
“making new connections and breaking other ones.”
