well...looking at it again, it reminded me of the famous stone garden in ryoanji.
there are 15 stones laid out on the garden, but from whichever directions you count them (except from the top view), you're only able to count 14 stones. meaning, we have to be contented with what we can see (or whatever), coz this world is imperfect. well, for the 15th stone, it's in the heart of the one counting. zen?
so..even dreams are not perfect? or one cannot have a perfect dream? :dunno:
