This is very interesting... I was first captured by your title, because it is also the title of an Elliott Smith song, and so I just wondered what your take on this memory lane could be. While filled with some sorts of symbolism and more abstract ideas, you introduce a blue sofa in the second stanza- is this somehow symbolic for something I did not pick up on? It just seemed somewhat out of place.
"And if I should fall down again
down memory lane on high heels"
These lines were for some reason especially striking to me because of the imagery of high heels... hmm.
"Walk its shadow like fallen ideals"
This one takes awhile to wrap your mind around- I like things that do that.
I'll have to read some more-
