So... Does anyone know what the "Dori" in the title could possibly mean? All of the -kano titles had meanings that actually had relevance to their respective contents.
"Dori" is most likely the loan word pronunciation of "dream" (doriimu). The main plot of the story is exactly that: a dream of an alternate timeline Madoka saw.
Well, "Yumekano" would also work, as "yume" also means "dream" in Japanese
