Could it be Reality?

What defines reality? As I read Snow Crash, I find that its hard to know what reality really is. If you are interacting with people isn't that in itself part of reality. What does the word reality mean? Is it life as we know it on Earth on solid ground, or does it have to do with the social morals and interactions we create. The Metoverse seems to be perfectly real. People interact, if something is drunk your mind simulates drinking or if information is handed over it changes you in some way. The mind controls how we react to life. If today you were told that the entire life you have created was just a stimulation and you were actually someone else outside of a computer...what would you do? Probably go into shock, but the point is, this may not be reality. Who has the right to say it is or it isn't? I feel like much of Snow Crash brings up points about how we see life, how we interpret it and what we see as real. The Metoverse isn't just a fun place to go, there are businesses and people being hunted down or thrown out of a club. Its just like real life. It's just like getting in your car and going into a city. So what makes it any different. Sadly I can't see how it's different. The mind is so much more powerful then we give it credit for because our other senses seem to have their own control over how we react to things, but they are controlled by our brains. All our senses don't have minds of their own, cells are connected to other cells that are connected to nerve cells that are all transmitted back to the brain. If they brain wants you to believe something or to see something or to feel something it lets it happen. We are a computer to say the least, we just don't have a grasp of everything that's going on inside of it. To me reality is what we make it. It may be here on solid ground, me sitting on my bed writing this small blog about what's real, or it could be an avatar created by myself inside of another computer controlled by my own brain. Reality is just a word, but we give it so much credit, we give it so much power that it doesn't necessarily deserve. Mostly because topics like this, scare us. Because in the end we realize how little control we have.
