Here's a classic for you: Robert R. McCammon's 1989 short story Something Passed By, as posted on his own site.
A disorienting story, set in a disorienting world - not just to you, the reader, but to its remaining occupants, too. something has passed by Earth, and nothing is the same anymore - and the changes keep happening, like a spring winding down to its inevitable conclusion. Which might not be the end, but merely the end of everthing as we've known it.
Great stuff, and much recommended reading.
The picture on the right is by a (Korean?) artist called 非 (hi), of whom very little appears to be known.
