Repetition and meaning of なくも


I am currently reading 天気の子 by 新海誠。There is a passage which I can't figure out
which uses the phrase なくも over and over. Other posts mention なく or も
separately, but not together (that I've found). I understand that "～もない （～もなく）
can mean 'not even～' or 'without (even) ～' but I was wondering what なくも means
instead. Also, why are there no commas between the repetitions. Sorry if this
has been asked/answered elsewhere. Here is the sentence:

ーような気が、しなくも、なくもなくも、なくもなくもなくもない。




This looks more like a creative choice to show an idea in the character's mind
flopping over and over, trying to figure it out. Kind of like - "...or that's
what it seems...or not? Or not not? Or not not not?"
