Some spiritualist, maybe even some buddhists, but at least most of the nde’ers, claim, that thoughts manifest in one form or the other, but mostly in enrgies or other manifestations of energy (vibrations).
An analogy in science would be that thoughts are quantastates of nerve quanta and can be a waveform (energy), and thus have, through quantum entanglement or electromagnetic induction, an influence on the world and on other people
That is also why a lot of the newage and spiritual and budhist etc. people recommend a mindfulnes meditation, in order to control oneselfs thoughts, and make the world a better place, by not influencing it with negative thoughts.
Maybe we should influence it with positive thoughts, and out of it following positive actions.
