Welcome, Jessie!
Hope to see more from you! Amazing, what can happen in
dreams, isn't it? A couple of times, I've dreamed entire
symphonies. (And wished mightily when I awoke that I could notate fast enough to get it all down before it eluded my memory--not a hope!)

wsieber--I had to look up numinous--thanks! The only thing
that comes to mind re: the o-oo sound is that it is like the howl of a wolf, and there are MANY numinous connotations around them, for sure.

BUT--in the same vein (no, I am not a vampire)--I just
thought of another word whose sound pattern is a lot like its meaning, so perhaps your incipient theory is correct: EERIE.
That is, if one sees something eerie, a common reponse
is: "Eee-ee-ee!".
