I am rereading The Sandman between Christmas and New Year before, I expect, reading some newly acquired Anderson novels and commenting on them.
When rereading, it is good to notice details not remembered from previous readings, like:
the alder man's "death traps" are like rope spider's webs in trees and the fact that one is torn tells him that a big death approaches from the south;
Delerium blows soap bubbles of different shapes;
Morpheus addresses the dancer as "Belili" and "Astarte" and each time she corrects him to "Ishtar" (she is really the Goddess);
"Tiffany Watches" is a pun.
