I recently discovered that I sometimes feel this strange "mirrored-eerieness", a tension that is in expectation of something good, even glorious. Whereas "eerie" tends to connotatively denote "premonition of something horrible", this "mirrored-eerie" would more connotatively describe a "premonition of rapture". It's like an ambigious "near-spiritual" experience.
I think, like "eerie", it would mostly serve as an adjective, but also as a noun that describes a feeling, like "terror", or "joy". Perhaps like "eerie", it could take on the form "____(i)ly". Otherwise, maybe "____ified".
From the examples I'll give, it's pretty flexible.
Alone in the chapel, the room became warm, the candles seemed to burn brighter, the stillness turned ________: soul and senses seemed at once to heighten and separate from the earth as though some apparition were moments away.
She stared into space, feeling ________, slowly disconnecting from the world passing by.
________: the kind of feeling you'd get if some holy spirit entered the room unannounced, or the soul of a lost loved one sat beside you.
I usually get this strange feeling listening to music, especially, if not exclusively, music that uses the "Lydian" mode--the "brightest major scale possible". It's not commonly used in popular music, simply because it just seems off. Ridiculously bright.
To understand the feeling of what I mean, here's two songs from Radiohead. Radiohead uses C Lydian a few times. Here it is in "Codex" at 3:44, and here it is in "All I Need" at 2:45. I started both clips a few seconds behind for context.
Even if you aren't a music theorist, you can just sense there's something about those parts that seems abnormally bright, heaven-gazing. The effect maintains the tension of "eerie", but the implication of something heavenly and not hellish.
"Anticipation" could work, but it seems weak, and could be used in either a positive or negative context. "Wonder" seems like it could word, but it lacks the notion of tension. "Excitement" is another close one, as it seems to denote tension, and usually positive tension (due respect to Bloc Party), so it's a possible candidate, I think. Either there is a word out there that connotatively merges the two ideas, one can be made, or a pre-existing one can be extended to include the merging of ideas.
If by a new word, "foreawe" seems like it could work. Literally, "before awe".
The silence and foreawe would soon give way to a glorious sight.
Suddenly the world felt farther from me: I stood foreawed, feeling like I would be taken from this earth to heaven itself.
Any suggestions? Thanks so much, -Jon
