I mean it doesn’t make sense. Imagine a real life person just listening or reading to a bunch of word salad and then immediatly lose all free will and get stuck on whatever last thought or characteristics they have but cranked up to 11 while going back to the world salad all the time. It really breaks my suspension of disbelief.
That’s kind of the point
The Hiss is more of a malignant meme that is trying to spread than a singular entity
The only personality it has comes from its victims ( Trench hiding it because his feelings of inadequacy, Dylan’s anger towards Jesse and Polaris)
and let's not forget
The Hiss was created by Alan Wake (or at least he influenced it, seeing as how the word salad is an experimental poem he wrote on college) as a result of his attempts to escape The Dark Place
It’s just the starter version of the Dark Prescence

I’d argue the-thing-that-once-was-hartman makes a fairly good case for the Hiss being on even playing field with the Dark Presence. Might well be the same thing filtered through a lake that is an ocean that loops that is a spiral
