If I am comfortable under the umbrella of any term to describe my beliefs, it would be animism (with a smidge of deism thrown in).
My belief system underwent a cataclysmic overhaul at the age of 10, when I nearly drowned. Until then, I was a good Catholic altar boy. After that, I began to ask questions and like many questioners, was unhappy with the Church's answers.
What burned into my brain was what I saw after I'd been dragged safely to shore and sagged, gasping, to the ground. I opened one eye and saw a few blades of grass growing amidst the mostly-sandy beach. I noted, with a growing sense of surprise and awe that not only was each blade of grass visually and completely distinct from its neighbour - but so was every single grain of sand. None were the same colour, shape or size.
As I marveled at this, I was struck with the inarguable certainty that each blade of grass and each grain of sand were connected - with each other and with the whole of everything else - including me.
I've spent much of the intervening 50 years distilling my experience and trying to follow the ripples. I didn't have the "classic" NDE with the white light and comforting sense of the presence of loved ones who'd gone before. But what I experienced was enough to convince me (eventually - it was a process) that all living things are connected. And more things are "alive" than most people would credit.
