There's nothing in your extra elements that precludes it was just your brain filling in the details. I think you're underestimating how capable we are of hallucinating things in proper spatial placing, even with motion going on. The strong connection feeling is often felt by LSD users, but is a separate phenomenon from being able to see through solid objects (the ground), and is just a feeling that your brain can arbitrarily assign to anything, including hallucinated objects. Ex. you can easily feel connected to things in dreams that have never existed in real life at all. I'm all for meditation and realization of the interconnected nature of all life, though. Keep at it.
