If you do not talk/think about something does it cease to exist?
Does “it” fade from existence due to lack of energy input? The phrases “Out of sight, out of mind” and “Ignore it and it will go away” come to mind.
By the same token, does focusing on something bring it into existence? Does “it” transform from concept to reality through energy input? The phrases “You have to believe it to see it” and “Your focus determines your reality” come to mind.
We are capable of both beautiful dreams and horrible nightmares. If the universe (as we perceive it) is the continuous dance of energy and matter transitioning from one state of being to the other, then everything is connected. That includes us.
Things can always be better, and things can always be worse. The phases “For every action, there is an equal and opposite reaction” and “Be careful what you wish for, you just may get it” come to mind.
