I definitely believe we're all psychic, it's an ability & sense we have like our other 5 senses. Some people are more in tune with their psychic abilities than others.
Unfortunately, we live in a society that is designed to take us away from our psychic abilities & separate us from our true selves, and is instead intent on distracting us with a world of materialism and consumerism. And therefore distracting us from the truth. It's no wonder the world is in the mess that it is.
Things are slowly changing though & people are starting to wake up.
I think the mental, spiritual, emotional & physical body are all interconnected. One can't survive without the other. And the healthier we are, the stronger we are mentally, spiritually, emotionally and physically. All of which feed into our psyche & our psychic abilities.
If the human race became less distracted with what's going on with the outside world ie all the materialism etc, we would become more connected on a spiritual & psychic level, and would live in a world of unity as oppose to it's current state of disunity.
Or at least, that's my opinion anyway. For what it's worth
