I don't know if I would call it a "language" (which to me implies grammar and some level of composability), but I suspect most
people have these hidden subconscious languages too.
Think about the "bouba"/"kiki" effect [1], or how the spells in Harry Potter sound recognizably "spell-like" even though spells aren't a real thing. (In the latter case, it's because they're phonetically Latin-adjacent.)
For example, here are some nonsense terms:
* Swith'eil Aerveid
* Karflon B43
* Hooboo skramp
If I were to ask you all which is a dangerous gas, a sex act, and an Elven city, I suspect there would be fairly wide agreement. Inventing words that are evocative this way is a fundamental part of fiction writing, especially in fantasy, horror, and sci-fi. There's nothing profound going on here, it's just that language recognition is fuzzy and highly associative even at the level of individual phonemes.
