I've googled for over 2 hours in all now, even gone to the library, and I still can't find the poem I'm looking for. I memorised it out of an American highschool literature textbook roughly 4 years ago, but have since sold the book. It's apparently called "The Storyteller" by Mark van Doren, but Google isn't helping in the least. As I recall, it goes something along the lines of:
He talked, and as he talked
wallpaper came alive
Suddenly, ghosts walked,
and four doors were five
...
and maps had mouths
Ships ran tackward
in a great drowse
Trains climbed trees
and then slid back down
Like the honey of bees
on the cold brick town
He had wakened the worm
in the world's brain
And nothing stood firm
until morning again
Of course, my memory could be rusty, but hopefully someone recognizes it. Anyone posting the poem or a link to where I can find it will receive a cookie and much thanks.
