I loved "October Skies" but had actually never read anything else by Oracle. I like Oracle's style of writing--descriptive and vivid without being overly wordy.

"Butterfly" is an interesting one for me--I have incredibly vivid, lucid dreams myself. (It's an odd feeling--I've questioned "reality" in my dreams a lot. Felt (or perceived the feeling of) physical pain. Weird stuff.)

I liked the recurring ideas of water (in the hospital, in the bathtub, Scully's tears and Byers offering her water, the water surrounding the chip; even the Wicked Witch of the West, who changes completely when water is added ;)). "Butterfly" has a kind of underwater feel--like things are shifting and changing in the light. Like dreams feel for me, too.
