Dancing on ketamine is such a foreign concept to me. At low doses, its more like sit quietly because my muscles are so relaxed and at high doses (still low doses compared to the article) its lie on the floor while falling through the void. I couldn’t imagine physical activity in either case.

I have a hypothesis I am developing around this - in that our actual sensory coming from our physical body is how our consciousness actually stays grounded to the here and now; there's more parts and layers to it than that, however my own experiences suggest this is a mostly correct statement. Another part of my understanding logically suggests that you could disconnect from the energy from a historical part of you, thereby returning only to what is strongly imprinted via your brain's biology - but shedding or losing the more subtle energies and vibrations that would other provide more pressure or a higher concentration in the equations-algorithm of your brain/mind. This might not make much sense without more context which will take a book to structure.
