Which is, I think, a separation between Aquinas and the JW annihilation view.
I was more than ambitious by equating the two. I'm happy to say wrong. The JW idea is based on some choad picking up a concordance and researching a few words in the Bible and then starting a religion based on nobody but him knowing what the Bible says, except the folks who wrote the concordance he skimmed. Aquinas was a stuffy and influential philosopher who thought a great deal about every tiniest thing. I think Aquinas is guided by his belief in Aristotle and the various causes, in this case, the formal cause, which is like a blueprint for a thing. It's a way to map a Bible term into a philosophical system. But the net result does seem to be that Dan ain't roaming around the sands of Egypt as a disembodied something when his body dies.

Absolutely.
Christianity has always allowed for similar experiences, visions and etc, but it doesn’t use them proof of anything—they generally involve some eschatological lesson or view.
You probably know more than I do here, how much has spiritualism influenced Christianity and Mormonism? For Mormonism, where there's smoke, there's fire; it usually gets it's ideas from somewhere else. Two example. The first is Jack Chick and his Chick tracts which I believe serve as a window into the mind of fundamentalist Christianity. In his tracts, when a person dies and meets God, an ethereal version of himself, clothes and all perhaps, rises from the husk and floats up to God and is either welcomed into heaven or dropped into a lake of fire. The depiction of the spirit is spot on what Mormons believe.
The second is the book
Return from Tomorrow, which was hugely popular among Mormons when I was growing up. I'm guessing it's the most famous Christian NDE book, it's certainly the most famous Mormon NDE book. The author, who becomes Christian after the experience, relates how he dies and is shown around the afterlife by a mysterious being who he thinks might be Jesus, but he's not sayin' that. The being shows him various scenes, one where people are studying and learning in libraries, listening to exotic music, and in those libraries are books of all kinds; tablets and parchment (not sure about gold plates). And then there are spirits hanging around places they can't let go in the mortal world, and then spirits fighting and arguing on some other plane. The being explains that even that good place isn't heaven and then takes him into space and shows him a magnificent city in the distance but they aren't allowed to go there.
That book became proof for every Mormon in the 80s that the Mormon version of the afterlife is true. It's not a perfectly clean fit, but it's sure closer to the Mormon version than any Christian version I'm aware of. So in seminary the book was plugged all the time; read about this guy who is not a member of the Church who experiences the afterlife and it's pretty much what we believe.
