Black Hole/White Hole Consideration

I'm watching the recent Veritasium video on Einstein's math regarding black holes, and they just put together a map where future is up and past is down. This got me thinking along wildly imaginative paths. The explanation is that if you are at the event horizon, then your past is outside the universe, in a white hole that can send information into the universe, but cannot receive any. By contrast, within the black hole you can receive information from the universe, but cannot send any.

What was most interesting about this to me is that the path to that position on the event horizon did not seem to be significant to the overall claim. Considering the perspective of the one at the event horizon, could this mean that, at that point, it could be said that you were never actually in "the universe" directly, but rather had been in a white hole the whole time? Would this mean that, if one's path would ever reach the event horizon in their existence, then one is already in a white hole without realizing it?

This is presently reminding me of a theory that I've heard, but have not looked into deeply, where the universe is better represented as the projection of something else, something outside of it. It may be that the source of this projection is the white hole location of one's consciousness, perhaps one's soul. If that were the case though, then the only way to receive information would be to cross into the black hole portion. 

For some reason this model is actually sounding more reasonable to be, with each aspect of it that comes to mind. I am now picturing each individual observer making a round trip, from white hole to black hole and back, in each fundamental moment, much like light traces the universe in each moment, in my light based theory of reality. This may be analogous to how the brain works, in some way.

Right away this reminded me of a recent threshold experience that I had with my council, where it felt like they were snickering at me because they had tricked me into "skateboarding the entire path through reality, twice, without me realizing it." I had on my best suspicious face at the time, but narrative sense started filling in how it might happen, and how it would be funny. I am reminded of my post of the skateboarder essentially orbiting past the event horizon, and how they would need to be able to continue to do this orbital loop as they approached the singularity. A singularity would essentially reach a cylinder shape on the pathway to it, but it did not seem like it could reach a cylinder of zero radius, meaning that the singularity itself could not be volumeless, but that the "bottom" (singularity) would have some kind of dimension, outside of universal spacetime. Anyway, I'm now realizing that it could be possible for one to be both the light in the universe and the observer, traveling the entire universe each moment as the light, and the entirety of their own black hole/white hole loop in a moment, as essentially perpendicular experiences. This would effective make their lim line and/or observation threshold the "event horizon" in the model, one that would travel with them. I believe that I have been duped by my council again, and what they actually meant was that I had been tricked into skateboarding all of reality twice, at the same time (once within, once without). -.- Not only that, but it seems like this pathway is meant to repeat forever, every moment, though fortunately with me traveling of my own accord simultaneously. It would make conveyance across this "event horizon" much easier and easier to understand, however... Words flying off the page indeed.
