There’s only one true reality that we all see our own reality from. Our world’s building stone is relativity that are minifestet by our freedom of choice. Our choosing on how we want to see the reality we live in is how the reality is reflected to us. The thinking, choices we make, actions we take, our upbringing and so forth is what makes the grounds for our choices which reflects the reality we perceive and live in. Therefore you can always change YOUR reality as it’s relative, though you can never change Reality as it just is and never anything else.
