Think that's at the core of Law of Attraction teachings. Quantum physicists are pretty close to proving what we continually think about, worry about, dream about, believe ... is what we create in our external reality as events, synchronisities .... both good and bad. Abraham teachings say if you hold something in your mind for as little as 17 seconds it's on its way to manifesting.

Only thing there's a short time delay before those things manifest in concrete reality so we often forget what we were thinking about.

Source always gives us what we hold in our minds so it's highly important to maintain a positive mindset to achieve those results. Easier said than done most of the time but is becoming more imperative as higher energy flows into earth.   

BTW read our solar system is supposed to be entering a photon band so that's likely where the energy is flowing from.   ;-)
