A 4-dimensional being, one that lives in the next dimension along, sees through everything and creates with 3-D materials, which is where light presumably (with a degree of scientific safety I believe) becomes a gel, something you could throw.
But in the 4th dimension, everything can be seen 'through' in this 3rd dimension, and a 4-dimensional being can be anywhere on the 3rd dimensional plane it wants to at the same time. This is how entities can watch us and even interact with us without our being able to see them. They simply live in a 'higher' dimension, or 'higher plane'. Non-locality isn't 'spooky action at a distance' to them, it's a way of life.
He has a great sense of humour, just tells it like it is, and some Mum must be very proud of him.
Thanks, Kai, for a great conversation and for sharing the subject this evening! Cheers!
