This had me LOLing a lot at the beginning. I think I saw Kyle Gass, Wilford Brimley, Murray Hewitt (from Flight of the Conchords), and a few Golden Girls, but maybe that was just me. I liked it quite a bit from the beginning, but I felt it got slow toward the end, particularly when the dog sings Dixie in some foreign French-type language.
Anyway, I think I get the plot for those who don't quite understand. It's a dream. It's a bunch of stuff that happened. They aren't related by linear logic, but by vague categorical, semantic relations. If you can explain all the symbolism in depth, you are probably a crazy person.
