When it's really quiet as I try to fall asleep, I'll sometimes hear faint sounds that seem to have been things I'd heard earlier in the day, with what's almost like a residual effect. It mostly seems comprised of co-workers talking, TV/radio broadcasts, and the vocal parts of songs (which doesn't include "Helter Skelter").

(2) Can you give some examples of how some common farm, food, or pet animals might rank on the list? [more inside]
