One of the stories was "The Library of Babel" by Borges, but I haven't been able to find any of the others among his works. Here is what I remember about some of them:
A man is walking along naked, his head is blown off by the wind. He (the head) comes to, looks around and sees his body standing motionless. By wiggling his jaw, he moves over to his body, then uses his teeth to climb up the side of his body until he can set his head back on his neck and continues his walk.
A man visits a gigantic waterfall, so large that no one has ever been to the top. While watching it he sees what looks like the remains of a huge disaster flow over, at the end the whole waterfall turns red.
A group of people with un-naturally pale skin, live as statues in museums.
There may have been others, but that is all I remember. They were all weird.
