I don't think of mindblowing writing as somehow substantially changing my worldview, or making me see things differently; I think of stories that are so perfectly written that I can't quite believe a human being wrote them. Stories where I feel ... exhilarated when I hit the last sentence.

To date, there are only two stories I've read that did that for me: "Come Lady Death" by Peter Beagle, and "The Chaser" by John Collier. There's a section of 3-4 pages in "Do Androids Dream of Electric Sheep?" that came close, and Terry Bisson's story "Meat" is also close for me, but not quite making it.
