Some spiritualist, maybe even 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 mainfestations of energy (vibrations). Analogy in science would be that thoughts are quantastates of nerve quanta and can be a waveform (energy) and thus have through quantum entanglement 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 and not influence with negative thoughts. Maybe we should influence it with positive thoughts and out of it following positive action.
