There was no denying its realness beyond the obvious ability to question it as I am now, but as is currently the case with my capacity to question the experience is real enough to not yield an answer.
Exactly.
If we can be blind within the dreams towards if it's real or not, how are we supposed to be able to know if this is real or not? It's essentially the Matrix question before it was appropriated to be about speed dating, and goes further on to the nature of questioning if the outer world the red pill sends them to is real or yet another simulation (suggested through Neo's powers IRL in the second film that both must be fake).
A key fundamental difference was that physics and causality fundamentally worked differently.
How can we know that the world we're sitting in right now is consistent when we cannot gauge consistency from within the dream? This blind spot is what led to people questioning the nature of Solipsism.
What was especially troublesome was the time each experience lasted. In all dreams but this one the experiences were ephemeral and discrete while this one was long lasting, it's whole duration seeming like it lasted decades and it was continuous.
Starting to sound like the passage of time idea in Inception.
More importantly though, we only exist in the moment with our perceptions offset behind it based on our reaction time. The notion of duration is only held in our minds, in our memories, so a fake memory could just as easily be simply convincing you that it's been a while... rather than it having been a while.
If you remember years passing, that's why it felt like it happened. This does not even mean that there's a set duration attached to it, but rather that you in but a moment's time were potentially able to convince yourself of said passage of time. It's less about what we've witnessed and more about what we believe we've seen in hindsight.
I'd only dreamed like that once, never before it and never again since, and the only reason I don't give it more merit is over Occam's Razor.
I am not sure Occam's Razor suffices as I can't find one experience fundamentally more complicated than the other when. I could use bias to say "I am here now" so I chose this one but that may only be true only in its own context.
I can rationalize that it was still a dream, but that it was influenced by something amiss with myself like if it were a fever dream or something (I didn't go to sleep sick or wake up sick, but as an example of what could offset the dreaming experience).
Anything I believe I saw in the dream is merely a belief, and I have no way of proving if once I revisited California if it matched up or if I simply reinvented the memory so that it'd match up. As a matter of heuristics I cannot take what I believe now to be identical to what I once believed, even if it's over small shifts in details happening without my awareness. Memory is suuuper malleable, and our certainty in it is purely an ego thing.
We only exist now, right now, right this moment, and everything we believe to have experienced only has as much validity as our ability to prove it to ourselves.
