Cover art for Dory lyrics by Grizzly Bear

a dory is the type of fish that dory is in finding nemo, but im sure he is referring to the type of fish, which is a saltwater fish being let loose into a bay, which i dont think saltwater fish can survive (at least tropical..) and an "eddy" is a current in water found in oceans.. but yeah, im pretty sure the song relates to being put into a situation that you dont want to be in etc etc, or at least something along the lines of that

A dory is a type of fish, but Dory the character is actually a blue tang, just like the clown fish is named Marlin. (nerd alert)

Anyway. :)

I think if you're thinking in terms of Dory the character, the song could be about losing yourself in the moment -- even if it's scary -- and forgetting everything, etc. But if it's just about two random dories, I think it becomes a lot darker. I agree, it makes me think of being put into an awkward situation and trying to escape/forget about it.
