Are there other realities?

 

 Are there other realities? 

When we are talking that reality can be the sum of all existent realities we must ask: is there some other realities than the reality where we are now? Reality is always a unique experience. But then we must realize that there is one remarkable thing in the human brain. 

The human brain can work in superposition. That means that we can do and think about different things. We can cook food and think about mathematical formulas at the same time. So in that case, we have two states in our brains. 

That means our way to realize things differs from dogs and other animals. Animals have only one state in their brain. They live here and now. In the human brain, the second state allows us to think abstract things without risk. The ability to think abstraction makes us unique. 

But if some animal starts to think about abstraction. That means the animal slides out of reality. And that thing puts our animals in danger. Because the human brain has different layers. Those layers can make many things at the same time. But if we do something the first time we must concentrate on that thing. 

Then we must understand another thing realities that we can observe might differ from realities that affect us. Reality and existence are things that are almost the same thing. The object can virtually exist. While a person sleeps those virtual objects turn into reality. They exist only to that person. Existence is a strange thing. 

We know that theoretically, a nightmare can kill a person. The emotional feeling or feedback from the nervous system can cause the situation. Where a person who has a weak heart can die because of nightmares. Because a person cannot separate reality and dream. That can cause a heart attack.

Can virtual reality turn real?

Sometimes people are asking can 3D virtual reality computer games turn into reality. Theoretically, we can think of the situation of those gamers of the game trapped in the electric chair. 

And if the character in the game dies, that launches an electric chair. That is the thing that can turn virtual reality into reality. That is one version of the thinking experiments. 

***********************************

Ants see reality differently than humans. In this case, the question is does the ant realize, and does it understand what it sees? And does reality require that actor realizes what the actor sees? This is an interesting question. Consciousness doesn't necessarily mean that actor realizes what the actor sees. 

When some insects see that something tries to slap them, it jumps away. So does the insect understand what it does? Maybe someday we know the answer. The fact is that reality is not the only certain thing. Things like hallucinations in mind. And 3D worlds in computer's memories are also reality. But they are not reality the same way as some forest is.
