A dreaming Spike issues the line, "I'm drowning in footwear!" in the series finale of Buffy the Vampire Slayer. My question is: does this line or Spike's dream have any deep meaning (like foreshadowing a future event or referencing to something that happened in the past) or is it just a silly one-liner?
On the one hand, dreams in Buffy are often prophetic and vague lines spoken in dreams often foreshadow future events (see dreams foreshadowing Dawn's arrival). On the other hand, there's the cheese guy.
I've done some poking around on the internet and found a shaky claim that this line is referencing the Shanshu (phonetically similar to "sans shoe") prophecy but this claim provided no source and it seemed like a fan theory more than anything else.
Mr. Whedon comments on the silliness of this line during the episode's commentary, but, at least in my mind, doesn't claim that it is just a silly line.
