There's also the story "Go, Go, Go, Said the Bird" by Sonya Dorman in the first Dangerous Visions which is like this, in a way.

There’s also “the ruum” by Arthur Porges[0]. We got as part of English class in high school, a long time ago.

Try not to read the Wikipedia as it might spoil the short story, there’s the pdf available on the web somewhere

		Yes! I remember reading that, as you say, a long time ago. This is the first time I’ve seen someone else reference it. I love that story.
