ぐわん: Is this a word? Drunken speech in manga


I'm reading a manga and am completely stuck on what is being said in the
following line of text:

> まわる = まる = circle ぐわんぐわん = ぐん？ ほわほわする = ほほする = cheeks

I've attached the page with the text highlighted in red. The scene takes place
where the girl is in a circle drinking party. The girl is intoxicated so I'm
guessing she's "thinking" drunkenly which means her words are going to be
slightly off, but I don't know enough Japanese to figure out what the real
words are. I don't know if all the "わ" are part of the actual word or if
they're placed in to show slurred speech.

Please correct me if I've misinterpreted the first and last part of the text.

They are all actual words. まわる is 回る, to revolve. She feels her surroundings
(or herself) are spinning. It can imply her thoughts go round and round (go
back and forth) in her brain. ぐわんぐわん is one of the
[擬態語](https://en.wikipedia.org/wiki/Japanese_sound_symbolism), it is often
used to describe a sense of **vertigo** or tinnitus (mix of ぐるんぐるん/ぐるぐる +
がんがん). ほわほわ is also a 擬態語. It's similar to ふわふわ, which is light, soft, fluffy
or **flowing** , but it sometimes implies warm feelings.
