https://en.m.wikipedia.org/wiki/Counter-Clock_World 1996, summer solstice, I attended a psychedelic trance party on the top of a small peak called Mooball (aboriginal name).
It was incredible, 10000W 4 way speaker system rising 9', and the vibration so strong it could be felt like seeing a torch beam with your skin.
That night I took a pretty epic dose, I think I had 300mcg LSD and a dose of DOB. At one point I stood watching the motion of the people dancing ecstatically to the thrumming boom of these amazing speakers, and started to see something.
What I saw was reverse time. I could see before the movement, like they were being pulled along like a tug towing a ship. The locus of causality was inverted.
In Apocalypse an interesting thing is discussed, about the existence of a reverse causality half of our universe, which spins in the reverse direction. The reverse is because it is the complement of our forward, one thing leads to another universe-half.
Even several key mathematical formulae in theoretical physics have solutions in reverse time. E=mc² is no exception, and it works on the root of the speed of light. The inverse of the mass, and soaks up the energy in our forwards half of the universe, as well as bleeding the other way to ours.
Phillip K Dick wrote an amazing story called "Counterclock World"
Actually, most of his books relate to his extraordinary ability to see this reverse time and the intangible forces, the spirits and principles. In fact, spirit means essence, and this, along with the reverse half, are the contents of the subtle realm referred to by religious texts.
It has objective reality, and we are sometimes able to see it. Like that night, high on acid I watched forwards time in it's reverse complement. Or maybe you could call it a component. Artists use this perception, training it is key to being able to accurately draw what we see.
The right half of the brain does this. It sees the opposite, where we see space, it is solid, where there is matter, is emptiness, and it allows the universe to move, yet always stay in balance, like the cross crawl of bipedal walking gait.
