All things are actually occurring simultaneously, co-existing in a big pool of potential. Every possible idea that you could have and every decision that you could make already exists. There is already a "probable you," thinking it and moving in that direction.
Every thought or idea that you have previously made or were even projecting has spun off and now exists in another parallel version of reality. All of these timelines are moving together, as one. All reality exists now. In considering the totality of your consciousness, you are experiencing many parallel realities, simultaneously.
