What a song. It's simultaneously delightful and emotionally draining, one of their best. Strong Jungian elements in it as well. In Jung's analytical psychology, the animus is the masculine inner personality populating the unconscious of a woman, the opposite of the anima, the female element in the unconscious mind of a man, which shows itself in the realm of a man's dreams. The "house absorbing fear and pain" beneath the woman's "pale and tender skin" could be taken to be her animus, and by "feeding on my dreams" the animus is trying to connect with the man's anima, whereas he wants the woman to "swallow down [his] sickest dreams", i.e. his anima. All of this represents their subconscious needs, their inexplicable desire to be together. Just one possible interpretation.
Sounds to me like a spade hitting the gravel. Given the previous song was 'How They Suffer', maybe it's a reference to death (specifically the death of Gira/Jarboe's parents)? Would fit with the general motif of 'loss' throughout the rest of the album.
the ending drone is the most sprawling sound ever, simply breathtaking. and when it comes back in "minus something"... fuck  I think of it like a motif that reappears throughout the album, sounds very similar to the intro of Helpless Child and a couple other points in the album too
"They ripped the ending from East Hastings (16:30-17:05), I can't believe this." not sure what you mean mate, since this was released a good while before east hastings 
I lol'd real fuckin' hard. Wow, iPaet. Fucking wow.
