My beliefs are centered around the notion that what we understand to be reality is a subset of a greater reality. This does not make existence or perception in general meaningful in the grand scheme of things, only from a limited scope. I speculate that the meaning of existence may actually be to distract from its own meaninglessness.
Our existence, according to my admittedly irrational belief system, can be likened to boarding a train with no windows that is flooded with amnesia-inducing gas. Once inside the train and amnesiafied, the subject will probably draw the simplest and most grandiose conclusions about the nature of the train and how they got there. The train would appear to be the entirety of reality. Is whoever built it the creator of everything? Did it spontaneously come to being and did you with it? Etc. This actually happens to children born in North Korean prisons (they have generational punishment) and they are bewildered upon discovering that a world outside exists at all (if they ever do).
From the subject's perspective, these are reasonable assumptions. But as an observer who exists outside the train system, they're absurd, and more mundane explanations are more plausible. It's more likely that you bought a ticket, or were abducted, or something along those lines, and that the causal chain is radically different between individuals. The kicker is that there is no way to know without knowledge of the system that the train system is encapsulated in, but the story of how we got here and where we're going is probably as convoluted and "normal" as it is within the system.
Like when entering the train, upon exiting it, each person is likely to end up in a different locale from anyone else, unless it's some kind of existential hijacking, and the reasons could be as absurd as anything else.
It's kind of new-age but I don't have a positive view of it. From our perspective, this condition may be near-eternal, but in the grand scheme of things it must be a blip, unless it's a perfect causal loop (which I doubt).
So the tl;dr of it is that I expect death to be too similar to living to be of any real comfort, and the common beliefs surrounding death are forged in unfortunate and inevitable ignorance.
