I love that Junji Ito has a bunch of stories that are metaphors for stuff like this. This one. Snail Girl being the same allegory as Metamorphosis. The tall actress being about the anxiety you feel when you know a coworker might ruin the business but everyone else seems to not care. The woman in the window and the window creeping closer is one of the ones most on the nose.

But then he also has the hot spring to hell which is literally “stupid man experiences stupid horror”. He just felt like making cheap horror that month, lol.
