But maybe it is just awkwardness in terms of the language.
I consider NF -- especially the Ni approach -- to have a mystical flavor to it, overlapping with spirituality. In my experience, Ni-strong individuals tend to be the "mystics" in Christianity and other religious faiths, where there's a broad intuitive grasp of spiritual/personal truth that provides strong guidance for how to live and what might be happening (broadly) in a particular situation. My INF friends in particular are the ones who typically describe having religious visions, as opposed to other types of people. But I wouldn't say anything supernatural is happening per se, although they tend to think there might be some profound religious experience; I think their ability to perceive what sort of changes/struggles are happening within a person, coupled with their metaphorical nature, results in those struggles and spiritual realities being perceived in dreams and symbols.
(This is kind of the spiritual mysticism that Jung himself was credited with. He had a strong Ti bent, too, it seemed, but it's plausible he was INFJ. I think the two types I see presented most often are INTP and INFJ, for him.)
