Our brains are programmed to perceive things as we normally see. We perceive vibrations as matter. We see it, smell it, taste it & feel it. That’s because we live in the third dimension.
If more people are more aware about this fact, then they’ll have a completely different outlook on life. However, people do get introduced to this. They just call it crazy-talk and reject it.
But we do hear vibrations. People just need to listen and accept it.

“Every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution and for life - weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way for them to get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.”   -Lawrence M. Krauss (2009)
