A DREAM by Jorge Luis Borges

In a deserted place in Iran there is a not very tall stone tower that has neither door nor window. In the only room (with a dirt floor and shaped like a circle) there is a wooden table and a bench. In that circular cell, a man who looks like me is writing in letters I cannot understand a long poem about a man who in another circular cell is writing a poem about a man who in another circular cell . . . The process never ends and no one will be able to read what the prisoners write.
