Short Answer: No, oh god no.

The various ways on how people come into contact with an after-life or Post-Mortem Existence, and the result is really varied, defined by a sociological culture that make up strands of different unified species; like Euroasian Wolves have more incommon with Euroasian Mice than either of the two have in common with their American or Indopacific counterparts/equivalents. As well as whatever events that transpire to cause them to die, or what happens to their body once everything stops beating.

The above character is Rachel who was elected to replace the person who took the role of Didymus in a local order of angels underneath an Archangel who works in the mortal realm as a Philosophy Professor that knew of Rachel prior to her death. I'm actually still tweaking and editing (as well as wanting to massively overhaul segments of the story/cosmos as too many of my characters are Albino; and I'm having issue with species diversity and other writing topics that are too nuts and bolty to talk about.)

But the character in my Icon, Julian(-Molkov de Spade) also died but rather than becoming an Angel, he instead became a Grim Keeper, which is part of an independent Cosmology/Supernatural species) that serve a completely different function as well as having power over life and death by whoever is dumb enough to answer questions the Keeper's ask, can also with questions that physical record 'erase' Supernatural beings by recording personal details. This plays up in dreams, when a supernatural entity dies in a domain where a Keeper takes refuge (worse if it's multiple keepers) they have to play this rather morbid game as per a set of rules; that is to return to the mortal realm the now deceased supernatural entity has to make a sacrifice; they can always pay in blood which is the 'cheapest' option but one that takes the longest (Problem as Keepers can still wake up and become relunctant to sleep if they aren't of a sadistic temperament, thus making someone return to the living realm is rather difficult.) or they can sacrifice an organ (Further rules and restrictions apply; for instance Angels can not lose their Heart, Kemetic entities can barely lose anything without suffering dire effects.) the scenario or game changes each time (Overlap with past situations do happen but are uncommon; Being tied down to a morticians table as the Keeper walks in wondering what's going on till it clicks they need to harm the person in order to help them.) of course answering their simple questions is always an option that they would 'really' love more people to utilize.

I think the weirdest post-mortem situation involves 'The Wine Tower' and other locations, as they don't obey standard laws of space-time or geometry but have this predatory internal architecture like carnivorous plants that trap people into and slowly pull them further into their labyrinth to "digest". Their is no remains, or soul left for recovery; I think at most there is a 'missing person' ad on a milk bottle a friend paid for or a notice in the paper, or a sad looking grey scale photo on the local supermarket window.

Other characters I know of, but won't name, can't actually die as they frankly don't exist and are mental apparitions, or are doppelgangers, a collective halluncination or projected by a supercomputer that's trapped them in the AI's circuitry and only wishes to fool them with an illusion of control by placing them in the real world. At least one is an artificial Construct known as a Golem, some are undead (but not as we known them; ie. No vampires.) and one character is an Alien Big Cat (Local Cryptozoological legend.)

Basically I'm a massive X-Files, SCP and World of Darkness Fan.

Also one character is a Robot built in the 40s in Germany, with a body conscripted from the T4 program. Also what's funny about Rachel is she is an impossible genetic hybrid and the weird 20th Century in-verse Science side of things is a whole other horror story.
