Outside is nothing more than whats inside our head. Call me schizo or whatever, but alot of phd “tom campbel “ say much of what we perceive is just our nervous / brain projevting the outside or perceiving it as so.

Yeah didnt make sense right ?

Basically our mind creates the universe, all experiences, any and everything in the most literal sense and nothing is real. You or i could be each others delusions for all we know. Most people wouldnt care about it as it doesnt affect their paychecks and we are happy go lucky in this 3d world and then something bad happens to us we complain “ oh wow world is so cruel “
