But what does it MEAN?

I had one of those incredibly elaborate cinematic dreams last night, some sort of Asian revenge/action movie with this really complex structure. It started with me as this aging musician helping this blind sculptor finish this big public artwork he had left unfinished years before, and there was a younger artist (who had his own story, pretty involved, that I don't remember) who didn't understand the background, so there's this flashback to when the sculptor wasn't blind, and he and I are attending some cultural conference at an enormous 70s style convention center, which is virtually empty but also seems to double as a poorly guarded armory for the military. The not-blind sculptor had to interrupt his work on the big unfinished sculpture to attend, and was already in a bad mood, but the bureaucratic niggling pushes him over the edge and he starts killing off the conference attendees. At first he does it surreptitiously, leaving a little monogram in blood - it's like an E or W - then he finds a cache of weapons and starts picking us off with a high-power rifle. I manage to avoid him and sneak up just as he's setting up some kind of futuristic laser weapon. I knock it over and the laser cuts across his eyes, blinding him. By then there are all these cops and military around, but in the chaos I manage to sneak him out. The funny thing is that I woke up at this point and my brain sort of compelled itself to shut down again so it could finish the story, circling back to the opening scene, the finished sculpture, and me playing the haunting theme music on some pan pipes made out of animal horns.

That's Zatoichi, the blind swordsman, pictured above.
