I mean I know very little theological stuff but did these people receive direct messages from deceased humans or did they receive spiritual visions of stuff like hell or angels or the virgin mary? Because I feel like those must be considered distinct in Catholicism. Communicating with the dead is like literal necromancy, or like a demon trying to infect your mind, right? Whereas seeing divine visions or insights through God himself, angels, Mary, etc don't seem like the same thing. Those sound more along the typical speed of what I'd expect.
